Can a secret be hidden in a 'safe' java class offering access credentials?

Question

This is a brainstorming question about what\'s possible in Java (or not). I want to know if it is possible to hide a secret within a class and prevent anymore from accessing

Answer 1

You can make a secret "hard" to access but you can't make it impossible. There's a saying (Bruce Schneier I believe): Against a casual user, anything works. Against a determined cracker nothing works.
