         * types ( Byte, Integer, Double, Float, Long, and
         * Short) each provide a class method named valueOf
         * that converts a string to an object of that type

        Integer integerObj = Integer.valueOf("100");
        System.out.println("integerObj    = " + integerObj);

        Double doubleObj = Double.valueOf("20.289");
