在Java中，获取给定月份的所有周末日期

这是带有描述步骤的注释的粗略版本：

// create a Calendar for the 1st of the required monthint year = 2010;int month = Calendar.JANUARY;Calendar cal = new GregorianCalendar(year, month, 1);do {    // get the day of the week for the current day    int day = cal.get(Calendar.DAY_OF_WEEK);    // check if it is a Saturday or Sunday    if (day == Calendar.SATURDAY || day == Calendar.SUNDAY) {        // print the day - but you could add them to a list or whatever        System.out.println(cal.get(Calendar.DAY_OF_MONTH));    }    // advance to the next day    cal.add(Calendar.DAY_OF_YEAR, 1);}  while (cal.get(Calendar.MONTH) == month);// stop when we reach the start of the next month
