How to Install and Use Eclipse IDE on Windows 11

Eclipse IDE is a widely used open-source integrated development environment primarily designed for Java development, but it also supports C/C++, Python, PHP, and many other programming languages through plugins. It is popular among students, enterprise developers, and open-source contributors because of its flexibility, extensibility, and strong community support.

On Windows 11, Eclipse runs smoothly when the Java Development Kit (JDK) is properly installed. Since Eclipse is Java-based, installing and configuring the correct JDK version is the first and most important step before launching the IDE.

This guide explains how to install and use Eclipse IDE on Windows 11, including JDK setup, Eclipse installation, project creation, and running your first Java program.
