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.
