Write a java program to print super class hierarchy at a current class which is passed from command prompt?

class Hierarchy {
 public static void main(String[] args) {
  if (args.length == 0) {
   System.out.println("PLEASE PASS THE CLASS NAME..!");
  } else {
   try {
    Class c = Class.forName(args[0]);
    printHierarchy(c);
   } catch (ClassNotFoundException cnfe) {
    System.out.println(args[0] + " DOES NOT EXISTS...");
   }
  }
 }
 static void printHierarchy(Class c) {
  Class c1 = c;
  String cname = c1.getName();
  System.out.println(cname);
  Class sc = c1.getSuperclass();
  while (sc != null) {
   cname = sc.getName();
   System.out.println(cname);
   c1 = sc;
   sc = c1.getSuperclass();
  }
 }
}

Output:

java Hierarchy java.awt.TextField
java.awt.TextField
java.awt.TextComponent
java.awt.Component
java.lang.Object
