用java控制台实现万年历－要求打印当前年月日的日历表格，要求对当天的日期单独标示

以下是用java swing编写的日历，很好用，在我所做的系统里就能够正常的使用

接下来是具体代码：

java 实现万年历

首先你要明白1900年一月一日是星期一

import java.util.*;

public class WanNianLi{

public static void main(String args[]){

Scanner input=new Scanner(System.in);

System.out.print("请输入年份：");

int year=input.nextInt();

System.out.print("请输入月份：");

int month=input.nextInt();

int totalDays=1,monthDays=0;

//计算总天数

for(int i=1900;iyear;i++){

if((i%4==0i%100!=0)||(i%400==0)){

totalDays=totalDays+366;

}else{

totalDays=totalDays+365;

}

for(int passedMonth=1;passedMonth=month;passedMonth++){

if(passedMonth==1||passedMonth==3||passedMonth==5||passedMonth==7||passedMonth==8||passedMonth==10||passedMonth==12){

monthDays=31;

}else if(passedMonth==2){

if((year%4==0year%100!=0)||(year%400==0)){

monthDays=29;

}else{

monthDays=28;

}

}else{

monthDays=30;

}

if(passedMonthmonth){

totalDays=totalDays+monthDays;

}

}////计算总天数结束

//打印格式，对齐

System.out.println("星期天\t星期一\t星期二\t星期三\t星期四\t星期五\t星期六");

int temp = (totalDays%7);

for (int p=0; ptemp;p++) {

System.out.print("\t");

}

for (int w=1; w=monthDays;w++) {

System.out.print(w +"\t");

if ((totalDays+w)%7==0) {

System.out.print("\n");

}

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……
