Anonymous classes enable you to make your code more concise. They enable you to declare and instantiate a class at the same time. They are like local classes except that they do not have a name. Use them if you need to use a local class only once.

While local classes are class declarations, anonymous classes are expressions, which means that you define the class in another expression.
