      System.out.println("Enter a string to print it's all substrings");
      string  = in.nextLine();

      length = string.length();

      System.out.println("Substrings of \""+string+"\" are :-");

      for( c = 0 ; c < length ; c++ )
      {
         for( i = 1 ; i <= length - c ; i++ )
         {
            sub = string.substring(c, c+i);
            System.out.println(sub);
         }
      }
   }
