第4次作业类测试代码+093+王坤煌
1.类图：
2.界面和相应功能：
新增weekDay()方法：
public static String weekDay(int m,int d,int y){
if(m == 1 || m == 2){
y--;
m+=12;
y--;
}
int week=(d+2*m+3*(m+1)/5+y+y/4-y/100+y/400+1)%7;
String rtweek = null;
switch(week){
case 1:
rtweek="星期一";break;
case 2:
rtweek="星期二";break;
case 3:
rtweek="星期三";break;
case 4:
rtweek="星期四";break;
case 5:
rtweek="星期五";break;
case 6:
rtweek="星期六";break;
case 7:
rtweek="星期天";break;
}
return rtweek;
}
新增lastDay()方法:
public static String lastDay(int m,int d,int y){
String lastday = null;
if(isLeapYear(y) == true){
month[2]=29;
};
if(m == 1 && d==1){
y--;
m = 12;
d = 31;
}else if (d == 1){
m = m-1;
d = month[m];
}else{
d--;
}
lastday = y+"年"+m+"月"+d+"日";
return lastday;
}
