java obfuscator

You can stop your jave code from being decompiled through obfuscation, correct?

Can anyone recommend a good java obfscator which I can use to stop my java source from being decompiled?

Can anyone recommend any bad ones so that I may avoid them.

ProGuard (on SourceForge) is a good open source one. There are also commercial options (like Allatori, DashO, Smokescreen) that may work better than any of the free ones. And no, ultimately obfuscators can not stop the decompilation.

So what can be used to stop decompilation?

That doesn't stop decompilation either (in fact, reverse engineering used to be a job of mine, primarily for resolving patent disputes).

It's difficult.

Nothing.

Here is a link to many different obfuscators.
