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:

运行结果:

Java编写程序,输入年份,输出本年度各月份日历

写了个简明的,

import java.util.Calendar;

import java.util.Scanner;

public class Test {

static public void main(String 参数[]){

Calendar c = Calendar.getInstance();

Scanner sc = new Scanner(System.in);

System.out.println("请输入年份:");

int year= sc.nextInt();

c.set(Calendar.YEAR, year);

c.set(Calendar.MONTH, Calendar.JANUARY);

c.set(Calendar.DAY_OF_MONTH, 1);

while(c.get(Calendar.YEAR)==year){

int wday=c.get(Calendar.DAY_OF_WEEK);

int mday=c.get(Calendar.DAY_OF_MONTH);

if(mday==1){

System.out.println("\n日\t一\t二\t三\t四\t五\t六\t第"+(c.get(Calendar.MONTH)+1)+"月");

System.out.println("---------------------------------------------------");

for(int i=0;iwday-1;i++) System.out.print(" \t");

}

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

if(wday==7) System.out.println();

c.add(Calendar.DAY_OF_YEAR, 1);

}

}

}
