枚举的简单应用（一）

枚举类

package com.yeepay.sxf.euma;
/**
 * 表示星期的枚举
 * @author sxf
 *
 */
public enum Week {
    Monday,
    Tuesday ,   
    Wednesday,  
    Thursday ,  
    Friday ,  
    Saturday,   
    Sunday,   

}

测试类

package com.yeepay.sxf.euma;


public class Test {
    public static void main(String[] args) {
        test1();
    }
    
    
    public static void  test1(){    
        //将枚举转换成==>字符串
        String ad=Week.Friday.name();
        System.out.println("将枚举转换成==>字符串："+ad);
        
        //将字符串转换成==>枚举
        String mon="Friday";
        Week mo=Week.valueOf(mon);
        System.out.println("将字符串转换成==>枚举:"+mo);
        
        //将枚举类内的枚举转换成==>数组
        Week[] eWeeks=Week.values();
        for (int i = 0; i < eWeeks.length; i++) {
            System.out.println("将枚举类内的枚举转换成==>数组:"+eWeeks[i]);
        }
    }
}
