Is there a free scripting tool

[BMD]

My first post here, I would like to know if there is a free and simi-supported tool for scripting. Something that will aid in the syntax and point out all the stupid things a beginner will do. I have used VB and VB like languages in the past and would like to learn java.
Any Help,,,,,,Please

Netbeans IDE has some plugins for scripting. Check the following links:
