Best Java IDE

Best Java IDE

Java is a popular programming language used by 9 million developers worldwide. It is the foundation for building systems like android and web applications, embedded processes, game development, and many more.

Like any programming language, Java needs a software environment to write and edit code. You can use either a code editor or an IDE (Integrated Development Environment) to edit and run your Java code.

Java has different IDEs like Eclipse, Xcode, JDeveloper, etc. But which one is the best IDE for Java development?

This blog will discuss some of the best Java IDEs and provide you with our best pick. So, if you want to learn more, continue reading.


IDE and Code Editor

Just like how you use software like Notepad and Word to edit text, developers use code editors and IDEs to edit code.

As the name suggests, Integrated Development Environments (IDEs) are integrated with a compiler, a code editor, and a debugger, which makes them perfect for development. Since you can edit, run, and debug your code, developers choose IDEs over code editors.

On the other hand, code editors are lightweight software that allows you to edit and save your code. However, most of them do not have a compiler; hence you can not run your code in them.


Requirements for a Good IDE

What makes an IDE a good IDE?

Here are some essential features an IDE must possess:

Syntax Highlighting

Syntax highlighting is a must-have feature as it highlights the code with different colors and makes the code more readable.

If you are a beginner, you will see a notable difference between highlighted and non-highlighted code, as the code without highlights looks dull.

So keep this requirement in mind when selecting an IDE for Java.

Automatic Code Completion

No programmer knows all the syntax of a programming language. They google the syntax and related codes while programming.

Automatic code completion eases the work of programmers by suggesting the complete code or syntax as you write the program. So this is a feature your chosen IDE must have!

Extensions

Extensions allow IDEs and code editors to add additional features. Since every application can require a different coding environment, you need to install plugins as your application demands.

So make sure you choose an IDE that allows you to install extensions.

Debuggers

Manual debugging is too much of a hassle. So an IDE needs to have good debuggers.

A good debugging tool saves a lot of your time and effort. So, always try to go for an IDE with an appropriate debugger.

  • It supports over 100 programming languages like JavaScript, Groovy, and Scala.
  • It has code editing, debugging, browsing, and refactoring features.
  • It is available for different operating systems and has a cloud edition, allowing developers to code in web browsers.
  • It supports real-time validation of errors as you write the program.
  • It allows you to set breakpoints that help you debug your code.

3. Apache NetBeans

NetBeans is the official IDE for Java 8, which is why it is one of the best IDE for developing mobile, web, and desktop applications.

According to Stack Overflow, 11% of voters use Apache NetBeans for Java development.

Here are some of the features of NetBeans:

  • It allows you to create, debug, deploy and test your application from its own environment.
  • You can format and define your own rules for all languages.
  • Linux IDE offers readymade templates for script writing.

What does Programiz Recommend?

At Programiz, we use Eclipse for Java development and recommend it for both beginners and professional developers.

Java is a challenging language to write code in. So its IDE must be capable of handling errors and helping you debug code efficiently.

Eclipse has real-time error validation, which warns you that the code might cause an error while coding. It also allows you to set breakpoints in between the program to troubleshoot errors.

Apart from that, Eclipse has Eclipse Marketplace, from where you can install varieties of plugins as your application demands.

Finally, it allows you to write code in web browsers, as Eclipse is available on the cloud edition.
