emnu还能继承接口，抽象方法
Season.SPRING.name()可以得到该对象的字符串，即“SPRING”；反之，由Season.valueOf(“SPRING”)则可以得到该对象，即Season.SPRING。
enum Season {
SPRING, SUMMER, AUTUMN, WINTER;
public static Season valueOf(int ordinal) {
if (ordinal < 0 || ordinal >= values().length) {
throw new IndexOutOfBoundsException("Invalid ordinal");
}
return values()[ordinal];
}
}
