In this article we will learn about inner classes and how can they be used to simplify event handling process along with sample Java programs. An inner class is a class which is defined inside another class. The inner class can access all the members of an outer class, but vice-versa is not true. […]
In this article we will learn about adapter classes which are used to simplify the event handling process. Sample Java programs are also provided.
