根據你的程式做了一個小修改

import java.util.Calendar;
import java.util.Locale;

public class TestDate {
        static Calendar c = Calendar.getInstance(Locale.TAIWAN);

        public static void processDate(int year, int month) {
                c.set(year, month - 1, 1);
                int maxdays = c.getActualMaximum(Calendar.DAY_OF_MONTH);

                System.out.println(c.get(Calendar.YEAR));
                System.out.println(c.get(Calendar.MONTH) + 1);
                System.out.println(maxdays);
        }

        public static void main(String[] args) {
                processDate(2007, 2);
        }
}
