"An anonymous class is essentially a local class without a name."

As you will see from the sample program in this lesson, anonymous class definitions are often included as arguments to method calls.

Button buttonC = new Button("C");

buttonC.addMouseListener(new MouseListener()
{//begin class definition
//Instance initialize
{System.out.println(
"Anonymous class C name: " +
getClass().getName());}
As is the case for an object of a member class or a local class(an inner class) (discussed in previous lessons), an object of an anonymous class must be internally linked to an object of the enclosing class.

Thus, an anonymous class is truly an inner class, because an object of the anonymous class cannot exist in the absence of an object of the enclosing class.
