Top Java IDE 2021 | Best IDEs for Java Developers

Java is one of the most popular programming languages and used by millions of developers worldwide. It is a general-purpose programming language that features an object-oriented approach. Since its first appearance in 1995, it has always been among the top languages in the field despite being much older.

Java was originally designed for TV systems but it was quite advanced for it at that point in time. Its creator James Gosling was highly impressed with C, CPP, and thus based on it he created this language of his which is still so popular as almost a major portion of developers code in it & also it is one of the 5 most used languages for development purposes around the globe.

IDE or an Integrated Development Environment is a software program that helps in easing the work to be done by a developer by providing tools and features, IDE normally comes with an editor, build tools, debugger, and much more. Nowadays all IDEs support intelligent code completion and intelligent syntax highlighting, also they provide support for VCS making a life of a developer a bit easier.

Best Java IDEs in 2021

1. NetBeans

Netbeans is an open-source Integrated development environment written in core Java. It is the most loved and used IDE by Java developers. It provides modularity to code as it supports modular approach i.e., it allows applications to be developed as modules (as a component of software). It is supported by all major OS.

NetBeans platform is basically a framework that simplifies the development of Java desktop applications. It is capable of installing modules dynamically. Besides Java, it also supports languages including PHP, C, CPP, and HTML 5.

NetBeans IDE is the official IDE for Java 8. With its editors, code analyzers, and converters, you can quickly and smoothly upgrade your applications to use new Java 8 language constructs, such as lambdas, functional operations, and method references.

BlueJ is rich in documentation and its documentation provides well support to its users and to beginners. BlueJ was mainly developed for educational purposes but is also suitable for small-scale Development projects in Java.

BlueJ was designed to support the learning of OOPs (Object Oriented Programming) as a result of what its team was able to differentiate it from other IDEs available. The interaction facility together with a clean, simple, and tidy User interface, allows easy usage and implementation with objects while in Development. The UML representation of all objects in the main screen at startup is one of the interesting features possessed by it.
Besides Java, it provides support in Stride which was added recently in 2017 while Java is since its Inception.

  • Runs flawlessly on Windows and macOS
  • Straightforward and Clean IDE interface
  • Allows interaction among objects
  • BlueJ 4 and later versions come with support for VCS


jGrasp a lightweight Development Environment which was designed focusing on the automatic generation of Visualizations in Softwares, considering it will further improve the Comprehensibility of software.
This visualization is expected to produce a static preview of source codes Structure and proper visualization of Data Structures at runtime.

jGRASP is written in Java and runs well on all platforms with JVM in it. Besides Java, it supports C, CPP, Objective-C, Python, ADA, and VHDL. It also provides a UML feature similar to BlueJ; it comes with an integrated debugger and workbench specially formed for Java. It is fully written and implemented in Java and was developed in Samuel Ginn College of Engineering at Auburn University at their department of computer science and software engineering.

  1. Before talking about its features and all about others too .I wanna say would I be learnt before having any skill regarding different lover level languages as now a days people got stuck while learning different languages simultaneously because that brings doubt in mind weather which one would be suitable for developing their own software or any simple program. This can be sought out by choosing any one of them from a combo pack .the features including object oriented purpose make Java developer easy to create their application with a easy and flawlessly but even though now this time engineer of java programming should make coding criterias less to use and get a lot automatically therefore time consumeness making application would be descend and temper of developer will be cool…

  2. Java is used in real world, starting from commercial e-commerce website to android apps, from scientific application to financial applications like electronic trading systems, from games like Minecraft to desktop applications like Eclipse, Netbeans.
