package com.tutorialspoint;

import java.lang.*;

public class ClassLoaderDemo {

   public static void main(String[] args) throws Exception {
     
      Class cls = Class.forName("ClassLoaderDemo");

      // returns the ClassLoader object associated with this Class
      ClassLoader cLoader = cls.getClassLoader();
    
      System.out.println(cLoader.getClass());
    
      // returns the parent ClassLoader
