What is the best and free Java IDE?
You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

Please see this description of some of the top IDEs. http://faq.programmerworld.net/programming/best-java-ide-review.html
A long appreciation for O'Reilly books also suggests I include this guide to Eclipse as a reference: http://oreilly.com/catalog/9780596100650/

M$Eclipse.
Eclipse is an open source extensible IDE. At present, it works well as a Java IDE, and includes Java development tools. It requires that you have the Sun Java runtime environment (JRE) installed. The IDE supports Windows XP, Windows 2000, Windows 98, Windows ME, Linux, Solaris, QNX, AIX, HP-UX, Mac OS X, and possibly other systems as well.
Netbeans
NetBeans is a cross-platform open source IDE for Java that comes with a syntax highlighting code editor that supports code completion, annotations, macros, auto-indentation, etc. It includes visual design tools (wizards) for code generation. It integrates with numerous compilers, debuggers, Java Virtual Machines and other tools.
These two rank highly because not only are they free they are easy to use and they are also cross platform,supporting practically all operating systems that we have out there.For a full list of Free Java IDE's you can check out the links below more so thefreecountry dot com that has a couple more to choose from,so basically you will have the opportunity to choose exactly what works for you,

Yeah, pretty much. Eclipse is *so* much better than other IDEs out there that if you look closely you'll see many of them are just a recompiled version of Eclipse with a new skin on them.
The only downside I've found with Eclipse is that it's "I'm not really a Java IDE, I'm an anything-you-want-IDE" insistence often makes it harder than it needs to be to figure out how to manage your projects, source control, etc... A true Java-only IDE might be a little bit easier to get up and running with.
