J2SE 枚举类型 [enum]

Week.java

代码；

/**  *  */ package com.b510.examples;

/**  * @author Hongten  *  * @time 2011-8-10 2011  */ public enum Week {  MON, TUE, WED, THU, FRI, SAT, SUN }

代码：

/**  *  */ package com.b510.examples.action;

import com.b510.examples.Week;

/**  * @author Hongten  *  * @time 2011-8-10 2011  */ 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;   }  }

}

运行效果：

Have a Rest ***************************** 得到Week枚举类型中每个常量的常量值 0 1 2 3 4 5 6 ***************************** 大家辛苦了，请努力工作！
