Java Frameworks – Advantages of Frameworks in Java 2019
In this Java Frameworks Tutorial, we will learn what is a framework in Java Programming Language with example and popular Java frameworks. Java is one of the most used and popular languages in the world. Also, there are many Java-based frameworks available for the developers that are used for making lives easy.
So, let’s start the Java Frameworks Tutorial.
2. What are Java Frameworks?
Java Frameworks can be defined as the bodies of pre-written code to which you are allowed to add your own code for solving a domain-specific problem. You can use a framework by making calls to its methods, inheritance or supplying callbacks, listeners etc.
Due to frameworks, you don’t have to do much of the coding for your application. It can be good or bad depending on your situation. The below diagram explains the Java frameworks.
Java Programming Frameworks all have the same syntax and can work with a similar concept, terms, and paradigms. With the help of framework, we can focus on the business logic of our apps, not on the writing basic functionalities like database connection or handling execption.
3. Advantages of Using Java Frameworks
Here you will see the advantages of using Java Frameworks:
One of biggest advantages of using a framework is the security. An extensive framework will generally have security applications. If you are able to find a security hole or a vulnerability you can directly head towards the framework’s website. There the security issue can be fixed.
Generally, extensively used frameworks will have a large support group or large forums where one can have their issues resolved and questions answered. They also have documentation part where one can understand the framework.
A general task can take you hours or days to complete with many lines of code. With the use of Java frameworks, these can be done pretty easily with the help of pre-defined functions. Therefore, the development becomes easier, quicker and effective.
Generally, the maintenance cost of the framework is low. Also, most used structures are already present and help the developer to code faster. If the coding is done faster the expense will become smaller in every way be it time or effort.
4. List of Java Frameworks
There is no problem in saying that Java is one of the languages that are in most demand these days. After getting to about the advantages of a framework you will now learn about some of the widely used Java frameworks.
The above chart shows the popularity of the Java frameworks. But let’s not jump to any conclusions based on the above chart. You will get the overview of each of the frameworks with analysis so that you can choose the one for yourself.
List of Popular Java Frameworks:
- Spring Framework
- JavaServer Faces
- Google Web Toolkit
a. Spring Framework
Spring Framework as you can see is way ahead of its competitors. Even though it was released a decade ago it still enjoys the confidence of the developer community. Spring is available as an open source framework. Spring Framework provides diversified support for developing a robust application with pace and ease. It is very lightweight and there are many extensions available to develop any Java-based application. It targets to make the development of J2EE application easier. A spring Framework promotes good programming practices by using POJO programming model.
b. Struts 2
Struts 2 is a successor to Apache’s Struts 1 which aims to ease the development of contemporary Java EE web applications easier. A Struts 2 is a comprehensive tool for developing enterprise-ready web applications. It does by optimizing the development process from beginning to end point and post maintenance too. It is for those who sweat over high-loaded systems such as broadcasting portals. Using the Struts 2 the testing takes less effort as it implements Action class plain POJO objects. In other words, it gives the developers the luxury of not to override or implement Action class.
c. JavaServer Faces (JSF)
JavaServer Faces or JSF is a web application framework. It intends to simplify the development of web-based UI for the server-based application. JSF also reduces the effort needed in creating and maintaining an application which will run on a server. It provides you to connect UI widgets with data sources to server-side event handlers. It has sets of UI components and provides API for developing components. JSF provides the reuse and an extension of standard UI components.
Vaadin is one of the popular Java frameworks that are used by the modern developers while creating applications related to business. A Vaadin uses GWT for rendering the end web page. It utilizes a component-based approach which takes off the burden on developers by communicating changes made to a browser. It allows programmers to build applications rapidly by providing an extensive set of UI components. Vaadin provides an opportunity to bind data using MVC or MVP by building a layout in Java, HTML or both.
e. Google Web Toolkit
Hence, in this session, we studied the Java frameworks and advantages of it along with various popular Java-based frameworks in the market. Also, we got to know about some of the Java frameworks in brief. Choosing suitable framework among the popular Java frameworks can be a tedious task. No matter which framework you go for remember the needs of your application and the tools needed for it.
