枚舉類型(enum)在Switch中的使用以及遍歷枚舉類型(enum)中的內(nèi)容
public class EnumDemo {
//定義枚舉類型
enum Month {
January, February, March, April, May, June, July,August,September,October,November,December
}
public static void main(String[] args) {
Month mon = Month.August;
switch (mon) {
case August:
System.out.println("這是個旅游的季節(jié)");
break;
case December:
System.out.println("這是個滑雪的季節(jié)");
break;
}
//循環(huán)遍歷枚舉類型Month
for (Month month : Month.values()) {
System.out.println(month + ", 順序: " + month.ordinal());
}
}
