        System.out.println("a is equal to b.");
    } else if (difference < 0) {
        System.out.println("a is less than b.");
    } else if (difference > 0) {

    }/*from w  w  w. ja  v a 2  s .  com*/

    System.out.println("a is " + ((a.equals(a2)) ? "equal" : "not equal") + " to a2.");

    System.out.println("The character " + a.toString() + " is "
            + (Character.isUpperCase(a.charValue()) ? "upper" : "lower") + "case.");
