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;  } }}
