枚举的使用

package chapter02;

public enum Season {
//定义四个变量
SPRING,SUMMER,AUTUMN,WINTER;
//定义一个私有构造方法
private Season(){

}

}

-----------------------

package com.bjpowernode.t02;

public class Test01 {

public static void main(String[] args) {
Season spring = Season.SPRING;


System.out.println(spring.name());
//返回枚举中常量的顺序，从0开始计数
System.out.println(spring.ordinal());

Season[] values = Season.values();//编译之后生成的方法
for(Season sea:values) {
System.out.println(sea);
}


}

}
