Decompling java classes

Noelie · 2006-07-20 14:10:13

Anyone know of any programs that can either decompile or 'look' inside of a compiled java class file? Thanks

Also, javap comes with the jdk (or whatever they call the sdk these days) - it does things a number of ways... you can either see all the various things like member data, functions etc. Or you can even get it to show jvm instructions - although that can be a bit hard to understand.

So, if you're hard pressed, (or just want to look at function signatures, even the private ones) you can use javap, but there are also the decompilers that Hobbes mentions.
