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;		
		
	}
