Anyone know of a good...

Buddy netbeans is not a programming languages to script. You have programming scripts like java script and VB script which are best in the market. If you are looking for IDE the eclipse is best one , if your computer have good memory in place the net beans will be better to execute programing language.

You could use JCreator Thiswebpage. Its a very handy tool for writing and compiling java code and executing it unlike the old fashioned note pad & dos prompt method. I use it to run my java programs. Its a small setup file so not a big headache to download actually and use. This is one i know of and i hope it servers your purpose regarding JAVA.

What are you after in an IDE? Personally I like both NetBeans and Eclipse. They are both very broken, but in completely different ways and so complement each other quite nicely. InteliJ Idea has some rather fanatic fan boys. I've not used the IDE myself but it does look very good. If you are a newbie however it might be worth not using an IDE, or using one very lightly. Knowing how to use the command line tools is an important skill. But scary if you don't already know how to use the command line. The other option for a newbie is Greenfoot - http://www.greenfoot.org/. I have only just become aware of it, and not used it myself but it looks quite interesting. http://java.sun.com/developer/technicalArticles/young_dev_learning_path/
