Is there a tool to deobfuscate java obfuscated codes?

The codes is extracted from a compiled class but they are obfuscated and non-readable.

First step would be to learn with which tool it was obfuscated. Maybe there's already a "deobfuscator" around for the particular obfuscator.

On the other hand, you can also just run an IDE and use its refactoring powers. Rename the class, method and variable names to something sensitive. Use your human logical thinking powers to figure what the code actually represents and name them sensitively. And the picture would slowly but surely grow.

Good luck.
