JAVA编写一个多功能万年历程序

import java.text.SimpleDateFormat; import java.util.Calendar; public class TestDate { public static final String[] weeks = { "日", "一", "二", "三", "四", "五", "六" }; public static void main(String[] args) { Calendar c = Calendar.getInstance(); c.set(Calendar.YEAR,2011);//2011年 c.set(Calendar.MONTH,0);//java中Calendar类，月从0开始， 0代表一月 c.set(Calendar.DATE,1);//1号 int day = c.get(Calendar.DAY_OF_WEEK);//获致是本周的第几天地, 1代表星期天...7代表星期六 System.out.println(new SimpleDateFormat( "yyyy-MM-dd ").format(c.getTime())); System.out.println("星期" + weeks[day-1]); } } 把以上测试代码写作一个方法 方法的参数名为年月日， 即可。当然Calendar 还有很多功能，比如一周的第几天，一年的第几个月……
