java獲取今天日期

A. java 計算日期 日期=起始日期+天數(周六，周日不算)

import java.util.Calendar;
import java.util.Date;

public class WorkDayAdd {
private static Date addWorkDay(Date date, int num) {
Calendar cal = Calendar.getInstance();
cal.setTime(date);
int mod = num % 5;
int other = num / 5 * 7;
for (int i = 0; i < mod;) {
cal.add(Calendar.DATE, 1);
switch (cal.get(Calendar.DAY_OF_WEEK)) {
case Calendar.SUNDAY:
case Calendar.SATURDAY:
break;
default:
i++;
break;
}
}
if (other > 0)
cal.add(Calendar.DATE, other);
return cal.getTime();
}

public static void main(String[] args) {
System.out.println(addWorkDay(new Date(), 1));
}
}
