请编写一个关于星期几的枚举WeekDay，要求： 枚举值：Mon,Tue,Wed,Thu,Fri,Sat,Sun 该枚举要有一个方法，调用该方法返回中文格式的星期。
package com.week.base;
enum Grade {
Mon("Monday") {
@Override
public String toLocalGrade() {
// TODO Auto-generated method stub
return "星期一";
}
},
Tue("Tuesday") {
@Override
public String toLocalGrade() {
// TODO Auto-generated method stub
return "星期二";
}
},
Wed("Wednesday") {
@Override
public String toLocalGrade() {
// TODO Auto-generated method stub
return "星期三";
}
},
Thu("Thursday") {
@Override
public String toLocalGrade() {
// TODO Auto-generated method stub
return "星期四";
}
},
Fri("Friday") {
@Override
public String toLocalGrade() {
// TODO Auto-generated method stub
return "星期五";
}
},
Sat("Saturday") {
@Override
public String toLocalGrade() {
// TODO Auto-generated method stub
return "星期六";
}
},
Sun("Sunday") {
@Override
public String toLocalGrade() {
// TODO Auto-generated method stub
return "星期日";
}
},
;
private String value;
//构造函数
private Grade(String value) {
this.value = value;
}
public String getValue() {
return value;
}
//抽象方法
public abstract String toLocalGrade();
}
测试
package com.week.base;
public class Demo1 {
public static void main(String[] args) {
String str = Grade.Mon.getValue();
String str1 = Grade.Mon.toLocalGrade();
System.out.println(str + "...." + str1);
}
}
