Here is a rough version with comments describing the steps:
// create a Calendar for the 1st of the required month
int 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
