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 AbstractClass { ... }

public interface InterfaceClass { ... }

// This is the concrete class that extends the abstract class above and
// implements the interface above.  You will have to make sure that you implement
// any abstract methods from the AbstractClass and implement all method definitions
// from the InterfaceClass
public class Foo extends AbstractClass implements InterfaceClass { ... }
