You could create a custom ClassLoader that decodes classes from random bytes. However, this ClassLoader itself is a class and needs to be loaded in a default way for JVM to understand it. And the user can decompile it, effectively getting to know how to decode your other classes.
What is done in practice is to use obfuscator. We use Proguard at our company.
