Eclipse is an open source programming IDE developed by the Eclipse Foundation. An installation package can be downloaded from https://www.eclipse.org/downloads. Eclipse is available for Windows, Linux, and macOS. You should download the latest version of the Eclipse IDE for Java EE developers.

You can either download a ZIP package of Eclipse or an installer package that executes the installation wizard. If using the ZIP package, you just have to extract the package to your local disk and it will contain an executable Eclipse.exe file that you can run by double-clicking on the file.
