Need a compiler or Viewer to view .class files

I have some class files that I open up in Note pad, but can not view them to know what they mean. What program do I use to view these .class in Java? Thanks.

You need a decompiler, to convert binary .class files, back into readable Java Source code files ( .java )"Jad" is a reasonable decompiler http://www.kpdus.com/jad.htmlregards,Owen
