You probably want obfuscation instead of encryption. Here's what google thinks:

Don't bother trying to encrypt classes. This is doomed to be utterly uselss as some form of protection. Since at some point, the JVM needs to be fed your decrypted classes, anyone interested in taking a look at them can intercept your already decrypted classes there. See this Article for a detailed technical explanation how any class encrypting can be circumvented easily.
