Write a Java Program to demonstrate use of nested class.

Program Code:

import java.lang.*;

class outer

{

int m=10;

class inner

{

int n=20;

void display()

{

System.out.println("m = "+m);

System.out.println("n = "+n);

}

}

}

class nesteddemo

{

public static void main(String arg[])

{

outer outobj=new outer();

outer.inner inobj=outobj.new inner();

inobj.display();

}

}

Output:

m = 10

n = 20
