Eclipse is a free Open Source IDE, it can be download from http://www.eclipse.org/ or the download page here.
The first package, Eclipse IDE for Java Developers, contains what you need to build Java applications.
Click the selected package to involve the mirror selection page, select your closest mirror site, start download and save it to any position on your machine you want.
After download, un-zip it on any position you want. It's the installed folder, "C:\App\eclipse\" on my setup.
When you run the application "C:\App\eclipse\eclipse.exe", you will be asked to select the workspace, it's "C:\App\eclipse\workspace" for me.
Remark: JDK is assumed to be installed before install Eclipse.
