Lambda Expression + Requirements to Java Classes and Interfaces

[Felix Schmidt]

Everybody:

I want to explore the benefits of lambda expressions for our open source 
software.

Here are some questions:
1. What are the basic requirements to a java object?

If I have such a abstract class

public abstract class AbstractClass {
   public void testMethod() {
      // do something here
   }
   public abstract void abstractMethod();
}

Is it possible to do something like:
AbstractClass class = #{System.out.println("abstract class")};

Or if this syntax is not valid, how could I modify either the 
AbstractClass or the instantiation?

Thank you
felix
