java输十二个月的代码的简单介绍

java 当前系统时间加十二个月怎么加

import?java.text.SimpleDateFormat;

import?java.util.Calendar;

import?java.util.Date;

import?java.util.Scanner;

public?class?Test?{

public?static?void?main(String[]?args)?{

Scanner?sc?=?new?Scanner(System.in);

Calendar?curr?=?Calendar.getInstance();

SimpleDateFormat?sdf?=?new?SimpleDateFormat("yyyy-MM-dd");

curr.set(Calendar.YEAR,curr.get(Calendar.YEAR)+1);

Date?date=curr.getTime();

System.out.println(sdf.format(date));

}

也帮我用java写个 输入年份打印出当年的12个月的日历 79453920

public?static?void?main(String?args[])?{

Calendar?c?=?Calendar.getInstance();

int?year?=?sc.nextInt();

c.set(Calendar.YEAR,year);

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

c.set(Calendar.DAY_OF_MONTH,1);

String[]?weeks?=?{?"日",?"一"?,?"二",?"三",?"四",?"五",?"六"?};

for?(int?i?=?0;?i?weeks.length;?i++)?{

int?offday?=?c.get(Calendar.DAY_OF_WEEK)?-?1;

for(int?i?=?0;?i?offday;?i++){

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

while(c.get(Calendar.MONTH)?==?Calendar.DECEMBER){

c.add(Calendar.DAY_OF_MONTH,?1);

java 编写程序,打印1-12月每个月各有多少天

Calendar cal = Calendar.getInstance();

cal.set(Calendar.YEAR, intYear);

cal.set(Calendar.MONTH, i - 1);

cal.set(Calendar.DAY_OF_MONTH, 1);

int value = cal.getActualMaximum(Calendar.DAY_OF_MONTH);

System.out.println(intYear+"年"+i+"月："+value+"天");

打印结果

如何在JAVA中 12个月

class Month

{

public static void main(String[] args)

String[] a={"January","February","March","April","May","June","July","August","September","October","November","December"};

System.out.println(a[i]);
