my advise is to download their Callisto product to ease the installation, as it comes with some of the main plugins already enabled. see eclipse.org/callisto/
eclipse is an open source java IDE. It's easy to use. But you must install JRE firstly. I have been using eclipse for four years, so if u have more question,just let me know Thanks
Thank you. I tried it and asked me for JRE and I executed one small application. But I want to give command line arguments. How this is possible. Thank you.
Just open Project settings, there you can find Arguments list. Are you writing your program using Java ?
