「java当月最后」java获取当月有多少天
本篇文章给大家谈谈java当月最后，以及java获取当月有多少天对应的知识点，希望对各位有所帮助，不要忘了收藏本站喔。

- 1、java一个时间的问题。
- 2、怎样用java编写日历
- 3、用java程序写出 接收一个年份和一个月份，判断得出该月的总天数。(用if语句完成）
- 4、Java日期操作问题，传入一个日期返回这个日期所在月的第几周，具体要求如下：
- 5、java中如何获取某个日期是当月的最后一天
- 6、java根据年月获取对应的月份工作日天数
java一个时间的问题。
System.currentTimeMillis();
这个方法返回的是long型，所以你应该是 long ft_acctime=System.currentTimeMillis();
如果要去的时间请使用如下类java.util.*;

用java程序写出 接收一个年份和一个月份，判断得出该月的总天数。(用if语句完成）
import java.util.*;
public class Test {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("请输入年份");
int year = input.nextInt();
System.out.println("请输入月份");
int month = input.nextInt();
if(month==2){
if (((year % 100 == 0) (year % 400 == 0))
|| ((year % 100 != 0) (year % 4 == 0))) {
System.out.println(month+"月份天数是29天");
return;
}else {
System.out.println(month+"月份天数是28天");
return;
}
}else if(month%2==0 ) {
System.out.println(month+"月份是30天");
}else if(month%2!=0) {
System.out.println(month+"月份是31天");
}
}
}
Java日期操作问题，传入一个日期返回这个日期所在月的第几周，具体要求如下：
import java.util.Calendar;
import java.util.Date;
public class test {
public static String getWeekOfMonth(Date date) {
Calendar cal = Calendar.getInstance();
cal.setTime(date);
//外国月份为0-11所以月份加一
int month = cal.get(Calendar.MONTH)+1;
int mweek = cal.get(Calendar.WEEK_OF_MONTH);
String d = month+"第"+mweek+"周";
return d;
}
public static void main(String[] args) {
System.out.println(getWeekOfMonth(new Date()));
}
}
java中如何获取某个日期是当月的最后一天
import java.util.Calendar;
import java.util.Date;
public class Test {
public static void main(String args[]) {
System.out.println(getLastDayOfMonth(new Date()));
}
public static Date getLastDayOfMonth(Date sDate1) {
Calendar cDay1 = Calendar.getInstance();
cDay1.setTime(sDate1);
final int lastDay = cDay1.getActualMaximum(Calendar.DAY_OF_MONTH);
Date lastDate = cDay1.getTime();
lastDate.setDate(lastDay);
return lastDate;
}
}
java根据年月获取对应的月份工作日天数
import java.util.Calendar;
public class Main {
public static void main(String[] args) {
System.out.println(countWorkDay(2018, 6));
}
/**
* 获取指定年月有多少个工作日）
*
* @param year
* @param month
* @return
*/
public static int countWorkDay(int year, int month) {
Calendar c = Calendar.getInstance();
c.set(Calendar.YEAR, year);
// 月份是从0开始计算，所以需要减1
c.set(Calendar.MONTH, month - 1);
// 当月最后一天的日期
int max = c.getActualMaximum(Calendar.DAY_OF_MONTH);
// 开始日期为1号
int start = 1;
// 计数
int count = 0;
while (start = max) {
c.set(Calendar.DAY_OF_MONTH, start);
if (isWorkDay(c)) {
count++;
}
start++;
}
return count;
}
// 判断是否工作日（未排除法定节假日，由于涉及到农历节日，处理很麻烦）
public static boolean isWorkDay(Calendar c) {
// 获取星期,1~7,其中1代表星期日，2代表星期一 ... 7代表星期六
int week = c.get(Calendar.DAY_OF_WEEK);
// 不是周六和周日的都认为是工作日
return week != Calendar.SUNDAY week != Calendar.SATURDAY;
}
}
