An anonymous class can be particularly useful in those cases where

• No reason for object of the anonymous class to exist in the absence of an object of the enclosing class.
• No reason for an object of the anonymous class to exist outside a method of the enclosing class.
• Methods of the object of the anonymous class need access to members of the object of the enclosing class.
• Methods of the object of the anonymous class need access to final local variables and method parameters belonging to the method in which the anonymous class is defined.
• Only one instance of the anonymous class is needed.
• No need for the class to have a name that is accessible elsewhere in the program.
