public void createInner()

{

InnerClass i1 = new InnerClass();

    }

  }

Method Overriding

public class parentclass

{

public void show()

System.out.println("Show method of Super class");

}

}

public class SubClass extends ParentClass

{

public void show()

{

System.out.println("Show method of Sub class");

  }

}

Purpose of Static Keyword

public class JavaStatic

 {

static int i = 10;

static void method()

{

System.out.println("Inside Static method");

}

public static void main(String[] args)

{

JavaStaticExample.method();

System.out.println(JavaStaticExample.i);

JavaStaticExample obj1 = new JavaStaticExample();

JavaStaticExample obj2 = new JavaStaticExample();

System.out.println(obj1.i);

obj1.method();

   }

}
