實作帶有構造方法的枚舉

package com.hbsi.day1;

public class EnumTest {

public static void main(String[] args) {

// TODO Auto-generated method stub

WeekDay1 weekDay = WeekDay1.MON;

System.out.println(weekDay.nextDay());

WeekDay weekDay2 = WeekDay.FRI;

System.out.println(weekDay2);

System.out.println(weekDay2.name());

System.out.println(weekDay2.ordinal());

System.out.println(weekDay2.getClass());

System.out.println(WeekDay.valueOf("SUN").toString()); 

System.out.println(WeekDay.values().length);

}

public enum WeekDay{

//sun(1)指明調用帶有一個參數的構造方法

SUN(1),MON(),TUE,WED,THI,FRI,SAT; 

private WeekDay(){

System.out.println("first");

}

private WeekDay(int day){

System.out.println("second");

}

}

}
