Date: 2013jan5 Language: Java Q. Java: Why am I getting this error from javac: error: illegal combination of modifiers: public and private A. Everything in an interface must be public. So this code will get that error:

interface Test { private class Hello { // ERROR: things inside an interface cannot be private int abc; } }

This is a (minor) flaw in the language if you ask me. You might consider using a class instead of an interface.
