Answer 4

Runnable
If you want to make a Thread (for doing things simultaneously), you just inherit from the Interface so the JVM knows:"Okay my small class, you want t be a thread? Let's do it! I know you are able to do it, because you are just like a real Thread because of that interface and so you habe the run()-Method, for example! Excellent!"
Any more questions? ;-)
