Insight on Java Beans and Enterprise Java Beans

Java is the most trusted and tested technology of the industry. It has been ruling the industry for more than two decades. This is because of the versatile nature of Java. Java developers can develop any type of application like hardware programming, desktop application development, web development, game development or even smart phone app development. Moreover Java is platform independent in nature i.e., we can run it on any platform. Hence there is a tremendous demand of Java developer in the industry. With time Java has modified itself to meet the expectation of the industry and hence it has been treated as the evergreen technology of the industry. To make the things seamless, there are many Java frameworks that help Java developers in building enterprise standard software applications for different domains. Today we will discuss to measure components of Java i.e., Java beans and enterprise Java beans.

Java beans: Java beans are classes that encapsulate a number of objects into a single bean. Usually it has two methods i.e., getter and setter methods. Through these two methods, we can interact with different events and properties of the application to give it an interactive look and feel. Through getter we can get some value from the application and with setter we can set it to the Java beans and then we can use it in the application. We can customise the user interface of the application through the Java bean without any hassle. We can also change different property values of the application for improve user experience. Well the Java bean is like a blank paper and it can be reusable in the application as a component.

Enterprise Java Beans: Enterprise Java beans are just like the Java beans with some additional features to make the development process of a higher standard. It is helpful in developing business standard Java applications. It is a server side component to encapsulate the business logic of a specific application. It helps in transition processing, concurrency control, asynchronous method calling, job scheduling and deployment of software components in server side etc. It has received a tremendous support and popularity from the industry in very less span of time due to its magical essence. Well it is just like Java beans along with an additional method i.e., a public constructor. This helps in developing highly optimised and efficient Java applications. Let us discuss few differences between Java beans and enterprise Java beans for better understanding in short.

Difference between Java Beans and EJB: EJB is always a remote object and it is invisible. On the other hand Java beans may or may not be visible depending upon the requirement of Java developers. Though Java beans can also be implemented in server side but it is always efficient to be implemented on client side only by the Java developers. On the other hand EJB is more powerful in handling server side components. Well Java beans does not have any types whereas enterprise Java beans are of two types i.e., entity beans and session beans. EJB may be transitional but Java beans don’t support transitions. Hence we can say Java beans is for customising user objects in local where as EJB is for high standard Java applications that needs server side customisation with more power and efficiency.

Java 8 and Its Features That Programmers Love

Java is one of the computer programming languages that are used widely for both web application, and mobile app development. The developers can write Java code once, and run it on multiple platforms without recompiling. So it becomes easier for them to create applications that work seamlessly with a variety of devices and platform. Oracle has released the version 8 of Java with a number of new features and enhancement. In addition to making programmers more productive, the new features further make it easier for them to develop and run a variety of Java programs.

New Java 8 Features that Make Programmers more Efficient and Productive

Lambda Expression and Functional Interface

Lambdas are one of the most important and talked about language changes in Java 8. It enables developers to pass functionality as a method argument. So it becomes easier for programmers to reduce the code clutter by using a single method class. For instance, if the programmer uses lambda expressions to add functionality to a button click action, the code will look both neat and compact. Java 8 further enables developers to define a functional interface that defines a single abstract method.

Nashhorn JavaScript Engine

The latest version of Java also comes with a new JavaScript engine called Nashhorn. The developers can use Nashhorn to write standalone JavaScript application in Java. As the Nashhorn is designed from the scratch, it performs better than other JavaScript engines, while being compatible with ECMA normalized JavaScript specification. The new engine will further reduce the gap between Java and JavaScript.

New Data and Time API

Java programmers often find it daunting to accomplish date and time manipulation. But with modern applications being accessed by users residing in different time zones, data and time management has become critical. Java 8 effectuates date and time manipulation through a new API. The Data and Time API included in Java 8 enables developers to use the package java.time package. The new package includes the methods required for making date and time operations simple and easy.

Extended Interface Declaration

Java 8 further introduces two new concepts to extend interface declaration. Now Java developers can extend interface declaration by using the default or static method. Unlike default methods, the abstract methods need to be implemented. But the abstract methods enable developers to add new methods to an existing interface without breaking the code’s binary compatibility. Thus, it becomes easier for developers to update existing interfaces without affecting the code written for older versions.

Pipelines and Streams

The Stream API introduces functional style programming into Java. The API further helps developers in writing clean and concise code. However, stream needs to be used alongside a pipeline. A pipeline can be defined as a sequence of aggregate operations through which stream propagates elements from a source. The programmers can now use stream and pipeline to access elements from various collections, and manipulate the elements by applying operations on them.

Base64 Encoding and Decoding

While creating modern applications, programmers have to use base64 encoding and decoding to efficiently store and transfer binary data over media. But Java developers have to use third-party tools to effectuate file transfer using base64 encoding and decoding. But Java 8 supports base64 encoding and decoding. So it becomes easier for programmers to effectuate the transfer of binary data without using any third-party tool or API.

Functions to Effectuate Bulk Data Operations for Collections

Java 8 enables programmers to effectuate bulk data operations for collections using two packages, i.e., java.util.stream and java.util.function. Despite being similar to an iterator, a stream comes with a number of additional functionality to process a collection more efficiently. Further, a stream can be used in a serial as well as parallel way. The developers also have option to use several methods and operations, provided by java.util.stream package, including max, min, count, filter, collect, reduce, limit, findFirst and findAny.

On the whole, the developers can avail the features of Java 8 to reduce the time and efforts required for building large and complex applications. However, it is also important for developers to spend some time to understand some of the lesser known features included in the most recent version of the programming languages.

How to make a successful career in Java

Why choose Java for your career? Java is the only technology in the industry that has survived for more than two decades with prestige in the industry. This indicates the potential of the technology in IT industry. You might be thinking why I am using technology word for Java instead of language. This is because java is a language that can be used in any domain and any platform in the industry. Hence java can be treated as one man industry. Hence there is a tremendous demand for java developers in the industry in different domains and sectors. Starting from hardware programming to modern smart phone app development can be done by java developers without much hassle. So there is a huge buzz for java in the industry and everyone wants to be a successful java developer at any cost. Let us see few success mantra for java developers.

Understand the core concept if you want to work in mobile industry: If you are trying to success in mobile app development using java then you must understand the core concepts of this technology. In fact to run a java program in any platform you need a java virtual machine or JVM. This is a tiny application that helps in executing the jar file in the hardware. But in modern operating systems like Android or IOS you have to consider a different way since there is no JVM in side. In that case you have to convert your Java development code to the platform compatible format like APK to run on Android platform. Similarly for IOS platform, a different approach is used while you are trying to build an IOS app.

Be strong on the front end development: If you are trying to be an efficient JSP developer then you must learn different tips and tricks for developing enterprise standard web applications in Java JSP. The knowledge process starts from the frontend development techniques. You must learn different frontend scripting languages and libraries for modern web application development. HTML, Java script and other java script libraries like JQuery, Twitter bootstrap etc are must learn things. So you must develop a strong grasp over these technologies so that you can develop industry standard responsive web applications.

Should possess strong command over back end programming! Back end programming contains the core logic and program flow of the application. As a smart java developer, you must possess a strong knowledge on the back end programming. Starting from database management, query optimisation and high degree of security features must be integrated in your application. To achieve these you must acquire enough expertise on these programming skills and should put continuous effort in discovering new and advanced tips and tricks of the language from different sources like website, social gossip etc.

Be passionate for your technology: Above all are useless until and unless you are passionate about your technology; because if you can’t enjoy your coding then you can’t be a good programmer. So you must have a passion for your technology and knowledge to be a successful java developer.

Java and its stability

Java means performance: Java is the only technology that has spread over almost all domains of the industry. It is everywhere in practical may it be a small set top box or a huge web application. It is spread in all domains like hardware, desktop applications, web applications, embedded system development and gaming consoles etc. What is more? It is also embedded in the new generation smart phones and tablets. This is because java is highly flexible and having tremendous potential in terms of performance and effectiveness. In fact java is platform independent i.e., you can run java application on any operating system or hardware; it just requires a small JVM. So java can be within a small video game device and it can be within a large mother computer.

Java is highly secure: Java is renowned in the industry as a high performance technology. It can develop scalable applications for different purposes of the user. Moreover Java development codes get converted into binary codes and hence it becomes next to impossible to crack a java application. Java applications are highly safe and secure for its exceptional security features. You can develop any type of application like desktop application or web application or hardware application and you will get enough scope to build secure application with different unmatched features of java language. No matter you are in which platform, a good java developer can build highly secure java application without much effort. Moreover it doesn’t need exceptional skill to develop enterprise standard software applications that are not only secure but also efficient and effective. For web developers, you can integrate 128 bit encryption technology to make your server highly secure and protect it from unethical access from hackers.

Most reliable technology: Reliability means how your application behaves under different critical circumstances. In embedded system development there is a special task known as interrupt service routine (ISR) to deal with various unexpected situations for the application. But in software application and web application no such proper guideline is available to deal with critical situations. But java provides enough programming opportunity to develop reliable java application without compromising on the quality of the application. A java developer can build reliable software application or web application for different platforms with the same efficiency and effectiveness. A java developer can develop applications for different platforms like windows, Android, IOS etc as per the requirement of the client. Moreover these applications are highly reliable in their respective places or platforms.

The end product is simply stable!! A programming language that provides enough scope for the developer in developing enterprise standard web applications that are not only efficient and super fast but also future ready is simply amazing. Java developers can integrate modern technologies like HTML5 and CSS3 and they can develop responsive web applications without much hassle. Moreover, cloud technology can also be integrated with java applications for better user experience. So, a technology that produces secure and reliable output is simply called as a stable product.

Why do companies look for best Java developers?

The only undisputed language on the earth: After the development of C and C++, the machine level programming got a magical change within it. Almost all the machines at that time were programmed using C and C++. Fortunately, both these languages were extremely secure and reliable since their codes get converted to the machine level binary codes after compilation. It ruled more that decades in the industry. But as we know nothing is permanent in the world and everything comes with some loop wholes. Modern developers find it difficult to write large programs for huge applications using C and C++. To overcome this issue a new language with a huge number of functions and libraries within it get born i.e., none other than java. Java has thousands of predefined functions and libraries which we usually need while developing any application. It decreases the development time for the programmer and hence and hence a productive tool.

Java developers have an all-time demand: Java has an extremely powerful concept i.e., platform independent. It makes java to be read by a machine once it get complied i.e., write once read anywhere. This platform independent characteristic of java gives it an overnight popularity among the java developers. Any size of application can be developed with the help of java without compromising quality at any stage of software development life cycle. Later on, understanding the future potential of web application, java developers got another weapon i.e., JSP to develop enterprise standard web applications. So java is now everywhere in across all domains and platforms.

Still industry wants better resource: Quality matters a lot and hence industry always demands for quality professionals in any technology and so the case for java developers as well. In fact the industry is driven by the quality developers. Due to its presence in everywhere i.e., hardware, software application, web application and mobile application hence, we must see a tremendous demand for java developers across the globe.

Best resource implies the best output: Few days back, one of my followers asked me which language to choose for his next web application development. I told him that the quality of your application can’t be determined by a language rather it is determined by the developers’ quality who works for it. Even if we develop an application in any poor language (Which is just an assumption because there is no practical POOR language) but, we can get a good product if we hire the best professionals in the industry. In this quality intensive industry, software farms always hunt for quality professionals in order to get better and better quality of output.

Next generation apps in Java: Well java developers can built modern web applications using technologies like HTML5, CSS3 and JavaScript for modern devices like smart phones and tablets. Java JSP developers can develop enterprise standard responsive web applications for the industry. Moreover java developers can develop mobile games and mobile apps for next generation computer device. The best part is we can develop simulators and emulators for different platforms like Android and IOS to test our application’s performance in these platforms. So java is well ready for the future with its large community of developers on its shoulders.

When are you getting your Java development Certification: Well certification gives an intangible hint about the quality and performance of the developers; so, it has always an extra advantage over others and hence both software organizations and developers are passionate for Java Certification, you should get one in order to showcase your resume among your peers.

The reason behind the demand of Java technology

Java is the only language on the earth having an undisputed record since its inception!! The demand for Java developers and java language is just like as huge as before even today. Java is successful in every circumstance onto which it is projected to May it be desktop application or web application or even hardware application. It leaves a beautiful essence with every application developed. Let’s discuss few crystal clear reasons that make java the most popular language in the industry.

Java for Desktop applications: Java has been receiving a tremendous popularity due to the quality it provides through desktop applications. There is no second choice when it comes about desktop application other than java. Java is extremely safe, secure and reliable for any type of desktop application development. Moreover, it is extremely reliable even for any size of application. Usually, it is best for huge data driven desktop applications and the quality of java application is simple unmatched.

Java for hardware applications: Yes, this was the point at which java has get born before decades. Java is the best option for hardware application. Though there are other options like C, C++ and Python; but, at the end of the day its Java that is really reliable and efficient in developing any type of hardware application for any need. It may be your set top box or Television, all come under the hood of Java.

Java for Web applications: In web industry, there are many languages to serve like PHP, ASP, ColdFusion or Python etc; but, if you consider quality and reliability there is no option other than java upon which you can trust. Any big data web applications may not handled as efficiently as java can. Java is superfast and hence for your multithreaded application, you must rely on Java without any second thought. Most of the big web applications are developed in JSP which is nothing but a web version of Java. Hence you have to adopt it.

Java for game development: Yes, Java is the best choice for game developers. Probably 90% of the games of the industry are developed in Java. May it be desktop games or mobile game all are developed in Java. There are millions of games developed in java. Moreover, the latest smart phone games are also developed in Java along with other languages. The best part is all types of gaming consoles are developed in Java (Except Play Station) because it needs extremely less memory to run a java JAR file through JVM.

Java for smart apps: With time, Java has changed itself to accommodate with the need and demand of the users and in that process it has also created a space in the smart app industry. Java developers can develop enterprise standard apps for different smart operating systems like Android, iOS or windows. A java developer can develop different types of apps like native apps, web apps and hybrid apps for all these platforms. When I say ALL platforms; I mean ALL because Java development is Platform independent!!

Java and Its Ever Increasing Popularity among Users

CodeEval recently published the list of most popular coding languages of 2015 based on hundreds of thousands of data points collected from various sources. Java is one of the top two coding languages in the list of widely used coding languages of 2015. Along with being object-oriented, class-based, and concurrent, Java is also a general purpose programming language. Java is one of the most dynamic programming languages that can be used for creating graphical user interfaces (GUIs), websites, internet applications, and mobile apps. There are also a number of features that make Java suitable for a wide variety of programming tasks.

What Makes Java One of the Top Coding Languages of 2015?

Object Oriented

Java is an object-oriented and class-based programming language. So the developers can reduce coding time by applying inheritance, encapsulation, polymorphism, abstractions and other OOPS concepts. The Java libraries are also designed based on several best practices and design patterns. They can further use the OOPS concepts to make systems flexible, extensible and modular.

Multithreaded

As a multithreaded programming language, Java can simultaneously perform different tasks within a program. Unlike other programming languages, Java does not require programmers to enable multithreading by calling system-specific procedures. So Java is used widely for developing large and complex software applications.

Supports Distributed Computing

Nowadays, most organizations use a network of computers. So the modern applications must be written in a programming language that supports distributed computing. As Java supports distributed computing, it becomes easier for developers to integrate network programs and applications. They can write the network programs in a manner that is as simple as sending and receiving data to or from a file.

Platform Independent

Java was initially popular due to its platform independence feature. It enabled programmers to write the code once, and run the same code on multiple platforms without recompilation. The Java applications are further run independently at both source and binary levels. So the developers can smoothly move Java applications from one operating system to another. The feature provides the flexibility required by modern websites, enterprise applications, and mobile apps

Secure and Reliable

Java makes it easier for developers to deliver software applications that are secure and reliable. The Java compiler can effectively identify the errors could appear during execution time. So the developers can easily identify and fix these errors to make the application reliable. Likewise, Java programming language, compiler, interpreter and runtime environment are built with security in mind. The security feature makes it easier for programmers to protect the Java application from virus and cross-site scripting attacks.

Rich API and Open Source Libraries

Java is hugely popular among developers due to its rich API. Along with being highly visible, the rich Java API helps developers in accomplishing a variety of programming tasks without writing loner lines of code. The developers also have option to use Java APIs for networking, database connection, XML parsing and I/O networking. At the same time, they can also use the open source libraries provided by Google, Apache and other organizations. These open source tools reduced the coding time and development cost.

Collection of Development Tools

The developers also have option to choose from a large number of Java development frameworks. The tools provided by Java frameworks help programmers in reducing the coding time and effort drastically. The growing popularity of Java as a programming language can also be attributed to frameworks like Eclipse, Netbeans, Maven, ANT, Visual VM, and Jconsole.

Community Support

Like other popular coding languages, Java is also supported by a large and active community of developers. Along with Java user groups and online forums, the programming language is also supported by several open source organizations. The community helps both beginners and experienced programmers to write modern applications in Java.

The massive popularity and market share of Android mobile platform also contribute towards the ever increasing popularity of Java. As Android apps can be written in Java, it becomes easier for enterprises to leverage the programming skills of Java programmers to create different types of applications. At the same time, the most recent version of Java comes with several new features and major enhancement to drastically reduce the amount of time and efforts required for building large and complex software applications.
