浅谈J2SE 枚举类型
public class TestEnum { /** * @param args */ public static void main(String[] args) { new TestEnum().work(Week.SUN); System.out.println("*****************************"); System.out.println("得到Week枚举类型中每个常量的常量值"); System.out.println(Week.MON.ordinal()); System.out.println(Week.TUE.ordinal()); System.out.println(Week.WED.ordinal()); System.out.println(Week.THU.ordinal()); System.out.println(Week.FRI.ordinal()); System.out.println(Week.SAT.ordinal()); System.out.println(Week.SUN.ordinal()); System.out.println("*****************************"); new TestEnum().workSwitch(Week.FRI); } public void work(Week day) { if (day.equals(Week.SAT)) { System.out.println("Go shopping!"); } else if (day.equals(Week.SUN)) { System.out.println("Have a Rest"); } else { System.out.println("Work"); } } public void workSwitch(Week day) { switch (day) { case MON: case TUE: case WED: case THU: case FRI: System.out.println("大家辛苦了，请努力工作！"); break; case SAT: System.out.println("星期六，一起去购物！"); break; case SUN: System.out.println("星期天，大家休息！"); break; default: System.out.println("搞错了！"); break; } }}
