Simple Programming in Eclipse IDE(Java 101)

Eclipse is an open-source, free Java-based software development program. It is one of the most popular programs among Java developers due to its being open source and its flexibility to be customized as per user needs via additions/removal of plugins.

It also allows developers to develop and test coding in various computing languages such as C/C++, Python, PERL, Ruby, etc.

It provides an integrated development environment (IDE) to the developers where they can use as many plugins to develop any particular software or app per their requirements.

It has an easy-to-use graphical user interface, making it a top choice among developers. It can be used for multiple operating systems (OS), including windows, IOS, or Linux.
