use of nested class in java code example

Example 1: Nested classes in java

// Anonymous inner class in java
abstract class Anonymous
{
   public abstract void display();
}
public class AnonymousInnerExample
{
   public static void main(String[] args)
   {
      Anonymous obj = new Anonymous() {
         public void display() {
            System.out.println("anonymous inner class example");
         }
      };
      obj.display();
   }
}

Example 2: use of nested class in java

In Java, it is possible to define a class within another class, such 
classes are known as nested classes. They enable you to logically group 
classes that are only used in one place, thus this increases the use of 
encapsulation, and creates more readable and maintainable code.
