      int cp1, cp2;

      // assign values to cp1, cp2
      cp1 = 0x008f;
      cp2 = 0x0123;

      // create 2 boolean primitives b1, b2
      boolean b1, b2;

      // assign isISOControl results of cp1, cp2 to b1, b2
      b1 = Character.isISOControl(cp1);
      b2 = Character.isISOControl(cp2);

      String str1 = "cp1 is an ISO control character is " + b1;
      String str2 = "cp2 is an ISO control character is " + b2;
