  // Create and Return StringBuilder class
  StringBuilder s1 = new StringBuilder();
  Class cl1 = s1.getClass();

  // It returns string representation of an 
  // object of class StringBuilder and String
  String str1 = cl1.toString();
  String str2 = cl2.toString();

  System.out.println("cl2.toString(): " + str2);

 }
