Java Interface-Implementation Pair [closed]

Answer 1

Now that Java 8 is out, this pattern is much nicer:

public interface StuffDoer{
    default void doStuff() {
        dosomestuff...
    }
}

public class MyClass implements StuffDoer {
    // doStuff automatically defined
}

Lambda got all the attention, but this was the most tangible benefit of Java 8 for our company. Our inheritance hierarchies got a lot simpler when we no longer needed to have abstract classes just to have default method implementations.
