- 1、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
- 2、JAVA日历代码,怎么做?
- 3、简易日历表,JAVA,布局的
- 4、Java编写程序,输入年份,输出本年度各月份日历
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");
