java跨年代码

java 中能够实现年月循环的代码

import java.util.Calendar;

public class MainTester {

public static void main(String[] args) {

Calendar calendar = Calendar.getInstance();

calendar.set(Calendar.MONTH, 11);

System.out.println("现在日期：" + calendar.getTime());

//再增加一天

calendar.add(Calendar.DAY_OF_MONTH, 1);

System.out.println("增加后的日期：" + calendar.getTime());

}

使用Calendar就可以实现,很简单,程序输出为：

java中用来判断平年闰年的代码怎么写?

import java.util.*;

public class Judge {

/**

* @param args

*/

Scanner input = new Scanner(System.in);

System.out.print("输入年份：");

int Num = input.nextInt();

if ( Y == 0 ) {

System.out.println(+ Num +"份为闰年");

}else{

System.out.println(Num+"份为平年");

这是我当年学java的时候找到资料.

java怎样判断两个日期之间相差几周(支持跨年)?

*?获取两个日期相差的天数

public?static?int?getTwoDatesDifOfDay(Date?big,Date?small){

Calendar?cal1?=?Calendar.getInstance();

cal1.setTime(big);

*?获取两个日期相差的周数

public?static?int?getTwoDatesDifOfWeek(Date?big,Date?small){

java 如何判断 一年的最后一周是否跨年

给定一个时间范围判断周的范围并且跨年为新的一周即跨年时分为两周

public class Week{

SimpleDateFormat myFormatterExt = new SimpleDateFormat("yyyy-MM-dd");

Date b_date = null;

Date e_date = null;

try {

// String week = HNFDCommon.getWeek(date);

//System.out.println(week+"week");

} catch (ParseException e) {

e.printStackTrace();

b_date = getFirstDayOfWeek(b_date);

e_date = getLastDayOfWeek(e_date);

while (b_date.getTime() == e_date.getTime() || b_date.before(e_date))

String week = HNFDCommon.getWeek(b_date);

System.out.println(week+"ddd"+myFormatterExt.format(b_date));

if(dayOfweek0){

dayOfweek = 0;

Date c_date = new Date();

c_date.setYear(b_date.getYear());

c_date.setMonth(b_date.getMonth());

dayOfweek = getDayOfWeek(c_date);

b_date.setDate(b_date.getDate() +dayOfweek-1);

if(week.equals(HNFDCommon.getWeek(b_date))){

public static Date getLastDayOfWeek(Date date) {

SimpleDateFormat sd = new SimpleDateFormat("yyyy");

Calendar c = new GregorianCalendar();

c.setFirstDayOfWeek(Calendar.SUNDAY);

c.setTime(date);

if(!sd.format(date).equals(sd.format(c.getTime()))){

return c.getTime();

public static Date getFirstDayOfWeek(Date date) {

c.set(Calendar.DAY_OF_WEEK, c.getFirstDayOfWeek()); // Sunday

public static int getDayOfWeek(Date date) {

return c.get(Calendar.DAY_OF_WEEK);

HNFDCommon 类中：

public static String getWeek(Date date)

String rtn="";

int year;

int week;

SimpleDateFormat sd = new SimpleDateFormat("yyyy-MM-dd");

Calendar cd = Calendar.getInstance();

cd.setTime(date);

year=cd.get(Calendar.YEAR);

week = cd.get(Calendar.WEEK_OF_YEAR);

//System.out.println("ttt"+sd.format(cd.getTime())+"bbb"+week);

int vmonth = cd.get(Calendar.MONTH)+1;

cd.add(Calendar.WEEK_OF_YEAR,-1);

week =cd.get(Calendar.WEEK_OF_YEAR)+1;

year--;

if(week 10){

rtn=year+"00"+week;

rtn=year+"0"+week;

return rtn;
