Java7中Switch语句支持String

Java7新特性Swith语句中支持String

实例：

public class StringSwitch {
    public static void main(String[] args) {
            System.out.println(getExpendedMessage("one"));
            System.out.println(getExpendedMessage("three"));
            System.out.println(getExpendedMessage("five"));
    }
     static String getExpendedMessage(final String token)
        {
            switch (token)
            {
                case ("one"):
                    return "Token one identified";

                case ("two"):
                    return "Token two identified";

                case ("three"):
                    return "Token three identified";

                case ("four"):
                    return "Token four identified";

                default:
                    return "No token was identified";
            }
        }
}

输出如下：

Token one identified

Token three identified

No token was identified
