import java.util.*;
public class OuterClass
{
   static class NestedClass

      public void display() 
      {
         System.out.println("static nested class example");
      }
   }
   public static void main(String[] args) 
   {
      OuterClass.NestedClass nested = new OuterClass.NestedClass();	 
      nested.display();

class Outer
{
   // outer class instance method
   void display()

      class MethodLocalInner
      {
         public void show()
         {
            System.out.println("in method local inner class " + num);
         }
      } // end of inner class
      // access method local inner class
      MethodLocalInner objInner = new MethodLocalInner();
      objInner.show();
   }
   public static void main(String[] args)
   {
      Outer objOuter = new Outer();
      objOuter.display();
   }
}
