Top 10 Popular Java Frameworks Every Developer Should Know in 2020

Java frameworks are essentially blocks of pre-written code, to which a programmer may add his code to solve specific problems. Several Java frameworks exist, all of which have their pros and cons. All of them can be used to solve problems in a variety of fields and domains. Java frameworks reduce the amount of coding from scratch that programmers have to do to come up with a solution.

Significant Advantages of Java frameworks

The programmer’s basic skeleton is provided by the framework, while the programmer only has to add blocks to customize the code according to the issue at hand. Java frameworks provide users with scores of advantages. Here are some of the significant advantages of Java frameworks.


 Security is among the most important features of Java frameworks. Java frameworks are generally very extensive. Scores of programmers have worked together to build the framework to suit the needs of an even greater number of programmers. A vast number of applications are designed to work on each java framework.

Given the same, it is evident that the framework will need to contain certain features to secure this data. Still, it is often observed that security flaws persist in Java frameworks even after the framework has been released for use. For such circumstances, these frameworks will have a portal to report these flaws so that they may be addressed in future releases.

Support Groups

Most Java frameworks, especially the frameworks that are used by a large number of programmers, have what is known as support groups. These groups are clusters of programmers using the same framework, which helps each other in resolving issues faced while using the framework.

Since the original developers of the framework’s customer service will seldom be enough to solve the issues faced by thousands of users of a framework, these support groups act as a community that helps solve problems in a much more swift manner. These support groups will generally take the form of online forums, and the framework may have multiple groups on different portals.


As mentioned previously, the amount of code to be written by the programmer is reduced significantly due to Java frameworks’ presence. Imagine having to write a Java program from scratch every time you need to solve the smallest of problems.

Now imagine the skeleton of a program, or even the basic structure of a program, being ready for you, with you only having to add lines of code to suit your particular needs. The second option will lead to great savings of time as well as energy. The efficiency in programming provided by Java frameworks is unparalleled by any other such element.


 Java frameworks have extremely low maintenance costs. Especially compared to the monetary savings these frameworks provided by reducing the time required for coding, the expenses associated with Java frameworks can often be minuscule.

The Play framework is primarily known for being user friendly as well as beginner-friendly. It allows for convention over configuration and is also able to show error messages in the browser itself. It is especially effective in high-performance applications due to its support of non-blocking I/O. It is certainly among the more failure tolerant frameworks and also showcases great flexibility.

3. Hibernate

Hibernate is an object-relational mapping framework. The Hibernate framework’s main selling point is that it is very efficient when it comes to solving an often faced problem when working with databases on Java – that of a mismatch between the handling of data by object-oriented programming languages and relational database management systems. This is done by developing persistent classes and allowing the programmer to communicate effectively with the database with minimal changes to the code.

Being able to perform database operations of objects in Java is an issue when it comes to most other frameworks, but the Hibernate framework slaves this problem very efficiently. It is used by a number of large companies, including IBM, Oracle, and Accenture, due to its advantages in portability and maintainability. It is free to use and completely open-source as well.

4. Dropwizard

Dropwizard is another Java framework that is used primarily for high-performance applications. Its main job is the development of RESTful web services swiftly and rapidly. The Dropwizard framework is extremely user friendly as well as versatile, given the fact that it is essentially a collection of various Java libraries. This also means that it is usable in most Java applications. All the dependencies are clustered into a single ecosystem in Dropwizard.

Dropwizard allows the programmer to perform swift prototyping natively. It also supports the highest number of Java libraries for any framework and is especially palpable for its vast support of Java’s open-source libraries. All of these features enable the Dropwizard to be among the most productive frameworks. Though it is still up and coming, the growth of Dropwizard has been prodigious over the past few years.

5. Struts

Strut is a framework for Java that has been developed by the Apache Software Foundation. It is based on Java Enterprise. The Struts framework is easy to use for veteran users of Java frameworks and supports for kinds of web applications developed in Java. Struts 2 is the more prevalently used version of Struts and is currently implemented by Infosys and Accenture. MVC based applications in Java are mostly developed in Struts 2 due to its use of the Java Servlet API.

Since Struts is primarily meant for regular and veteran Java web developers, it also contains a wide variety of advanced features that can be implemented in the programmer’s web application. Among the most useful features is the fact that Struts framework applications can be integrated seamlessly with applications built on other frameworks as well.

6. Blade
