what does java run time environment contains? which tool is better!!? i felt eclipse is little bit complex!! any other tools!?
JRE won't do the trick. you'llned JDK if you want to compile your programs. In case everything fails, download the Processing IDE. You'll be up and running as soon as the download finishes: no Installation, no Path to set: just launch the ide, code and run your program. https://processing.org
use netbeans. It is easy than eclipse
