Eclipse is an open source, integrated development environment (IDE) used for software development, including application development, web development and embedded systems development. It is written in Java and runs on multiple platforms, including Windows, Mac OS, Linux, and Solaris. It is also used for developing mobile applications for Android, iOS, and Windows Phone. Eclipse is highly extensible, allowing developers to customize the environment to suit their specific needs. The Eclipse platform provides a powerful set of tools for developing software applications. It includes an integrated development environment (IDE), a source code editor, a debugger, a compiler, a language support system, an operating system emulator, and a version control system. It also provides plugin support for a variety of tasks, such as software testing, automated builds, and code coverage analysis. Using Eclipse, developers can quickly write and debug code, create GUI applications, develop mobile applications, and deploy web applications. Eclipse supports a wide range of programming languages, including Java, C/C++, JavaScript, Python, COBOL, Groovy, and many more. It also includes support for various web technologies, such as HTML, CSS, XML, and JSP. Eclipse provides a wide range of plugins and extensions that allow developers to customize the IDE to suit their specific needs.
Visual Studio Code only allows you to write code, not even run it.
The IntelliJ IDEA community is open source under the Apache 2.0 license.
More polished and easier to use compared to Eclipse
One of the best alternatives to eclipse!
is still the gold standard for C++.
Netbeans is in my opinion quite similar to eclipse but easier to learn and use. The refactoring code (when renaming a variable) is very simple. Just do Ctrl + R and the rest will follow. I have some experience using Netbeans to code Java. Right now I'm eager to try it for coding C as well.
They are almost identical, from how they manage, organize, available programming languages, tools. The differences only appear when digging through both.
Discontinued Aptana is still under development on GitHub but the latest version, 3.6.1, was released in October 2014. It lacks Java 8/9 features, as well as more recent JavaScript and HTML 5 features.

Visual Studio Code has quickly become one of the best cross-platform editors on the market. I'd say it's somewhere between a full IDE and a simpler editor - I love it!
