How to create an object of an abstract class and interface

Question

How do I create an object of an abstract class and interface? I know we can\'t instantiate an object of an abstract class directly.

Answer 1

public abstract class Foo { public abstract void foo(); }
public interface Bar { public void bar(); }
public class Winner extends Foo implements Bar {
  @Override public void foo() { }
  @Override public void bar() { }
}
new Winner(); // OK
