What is Java framework? And How it helps programmers

If you want to build a web or complicated web applications, this will waste the time when coding from the beginning to the end. So Java frameworks are the best solution to create web applications or software. In this article, BAP will introduce the basic understanding of Java framework, and recommend some famous frameworks on the market as well.

1. What is Java Framework?

Java framework is considered as a framework made up of code, library in order to minimize the effort of developing applications that provide the features like model, API. There are many Frameworks for Backend, Front end, Mobile application, and Website. But the most famous are Web and mobile Framework.

Furthermore, Java Frameworks look like materials that programmers are able to use to build their application, or software. Which means that developers will take the available designs and put it steps by steps to create the final products.

These frameworks don’t require highly high skills, so programmers still can generate the qualified products. Different frameworks will be used for different applications, or software. And the responsibility of programmers is to know which frameworks will fit with their software or applications.

2.What is Java library ?

This is not the new term and very popular as Framework. Library is a set of built-in functions and classes that developers can apply in the process of forming the applications, or software. Moreover, each function, class in the library has its own usage and is used to serve a specific job.

Whether or not you use the library, it doesn’t affect the completion of the project that you are programming, as Library doesn’t play the key component. However, when you can understand how to use the library, you can upgrade the quality of software, or applications.

3. Difference between Java framework and library

When a library is a collection of classes and functions, then Java Framework is a set of programming libraries. Combined with many other tools for effective web development including compiler/interpreter, command line tools,….

There are some differences between Java Framework and library:

  • For Java Framework, the code blocks in the framework will send requests to the programmer’s code.
  • For Java Library, programmers’ code blocks send requests to the library’s code.

Specifically, the Library works like the client/server model, it means that the client sends a request, the server receives the command and responds to the result. Once using the Framework, this relationship is reversed. Taking a PHP framework like Laravel as an example, the code in the Framework will send a request to the programmer’s application code with the design principle “Inversion of control”.

4. What is the Java web framework?

Web Framework is a software framework designed so as to support the development of web applications including web services, web resources, and web APIs, providing the necessary functionality to create a Web application

Using Java web app framework, programmers can develop thousands, tens of thousands of lines of code written by professional engineers, even newbees of programming will be able to develop Web applications in the short-term time. Building an application according to the Web Framework, programmers can easily add various functions, and prevent network attacks without writing a large amount of codes.

5. Top 10 popular Java web app frameworks on the market

5.1 Spring

java framework trends

Spring MVC is one of the oldest Java Web Frameworks, and people trust it most. Until now, it is still being utilized and constantly changing, developing more changes along with Java.

As for software engineers, it provides a great toolkit for web apps development and shaping, as well as enhancing accompanying security features. This is a really large Web Framework that allows you to complete any potential task or projects.

Thanks to their modularity, the tools will help you write a lot of clean and accessible code. There’s also a huge amount of documentation, and the active community helps you out if you have any questions about what to do or how something works.

Thanks to their modularity, the tools will help you write a lot of clean and accessible code. There’s also a huge amount of documentation, and the active community that helps you out if you have any questions about this software.

However, the major minus of this is its complexity, and if you are newbies of Java Web Development, Spring will not be the best choice for you, because you must have experience and knowledge in advance.

Advantages:

  • A source of documentations
  • A lot of people use it
  • Allow you write codes and access it with ease

Disadvantage:

  • Newbies need to have more knowledge of Java

5.2 Struts

Struts is a free and open source framework for creating simple Java apps. It is mainly used to generate the foundation for web apps, and works on the pattern MVC (Model-View-Controller).

However, if you use Struts, you will find that the framework is not very flexible and using it means you need to get used to the set of the coding and design rules of web apps. This will be a huge minus for those who are accustomed with certain methods, and Struts wants you to use their own set of rules as well.

Pros:

  • Free and open source
  • It works very fast
  • People are easy to test new codes

Cons:

  • There are rules
  • This is complex framework
  • Not flexible

At present, Struts launched the new version called Struts2. This is not only the next version of Struts 1 framework model, it is a complete upgrade of the Struts architecture, simplifying the previous Struts framework such as minimizing the configuration file or using annotations to replace configuration files

Struts was published by Craig McClanahan, and Apache supported it from May, 2000. In June , 2001, Struts 1.0 was released and then the Struts 2.5.20 version was announced on 14/01/2019 that has been called Struts 2. This version is the combination of Webwork Framework and Struts 1. Moreover, Struts Framework is supported by 2 main components which are View and Controller. These model components were not assisted a lot before, because Strut Framework aimed at connecting or retrieving to processing components. And now, this is evaluated more the Struts1 with the prominent points:

  • Using both annotation and minified XML configuration file
  • Using the new Object Graphic Notation Language (OGNL) to replace for JSP’s EL
  • Using single taglib so as to replace 4-5 tanglib sets in Struts1 Framework and JSTL 1.1. In JSP.
  • Tag support: Struts2 has improved new forms and tags to help developers write less code
  • AJAX support: Struts2 recognized the takeover of Web2.0 technologies, and integrated AJAX support into the product by creating AJAX tags that have function looking like Struts 2 tags.
  • Easy Integration: Integrating Struts2 with other frameworks like Spring, SiteMesh, which is easier than ever.

With some above functions, Struts2 is evaluated more than Struts1 from Programmers.

5.3 Hibernate

HIBERNATE Java Framework – Source: Twitter

Hibernate is a very popular Web Framework in terms of quality and various options as well. Hibernate is a place for object-relational mapping, which means that it transforms data between two disproportionate systems, and let them work together through other object-oriented programming languages. Apparently, in this case, the language here is Java.

So, you can use Hibernate to work with existing databases, optimize the web app code. It is extremely convenient and useful if you have to deal with a lot of databases that are difficult to use or be incompatible.

Besides, the speed and the ability to work with a lot of data, Hibernate is very easy to scale no matter how big of small your software is, or how more or less users apply. If you are designing a piece of software for 10 to 20 users, or hundreds of thousands of users, Hibernate is the perfect choice.

Furthermore, Hibernate is easy to edit and you can do anything with it. However, one of the biggest drawbacks of Hibernate is that restarting the Web Framework and then coming back will take a lot of time and be slow; even if the power is turned off by mistake, you get risk losing data.

Pros:

  • The framework works so strongly
  • Easily transform data
  • The speed of software is high
  • Easy-to-scale
  • Easy-to-edit-and-control

Cons:

  • The ability of Restart is slow
  • Highly getting risk of data
