Brief: This article guide highlights the most widely used Java IDEs for developing Java applications.
Java is a high-level, object-oriented, and general-purpose programming language that is widely used to build robust and secure web and desktop applications. Most developers prefer working on an IDE that simplifies writing code and maximizes productivity.
So, what is an IDE?
An IDE (Integrated Development Environment) is a software application that combines a comprehensive set of development tools and plugins into a graphical UI that makes writing code easier and more efficient.
