java月历

发布时间: 2021-03-25 23:57:28

⑴ java输入一个日期，编写程序输出这个日期所在年份和月份的月历

importjava.text.ParseException;
importjava.text.SimpleDateFormat;
importjava.util.Calendar;

publicclassTest29{
publicstaticvoidmain(String[]args)throwsParseException{
Stringdate="2015-7-1";
SimpleDateFormatsdf=newSimpleDateFormat("yyyy-MM-dd");
Calendarca=Calendar.getInstance();
ca.setTime(sdf.parse(date));
System.out.println("年："+ca.get(Calendar.YEAR));
System.out.println("月："+ca.get(Calendar.MONTH));
}
}

⑵ java输出一个月的月历

import java.util.*;

public class Year{
/**
*判断是否为闰年
*/
public boolean getIsRun(int year){
if((year%4==0 && year %100 !=0)||(year%400==0)){
return true;
}
return false;
}

/**
*返回某年某月有多少天。
*/
public int getDay(int year ,int month){
int[] day={31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};//闰年月份
int[] day1={31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};//普通月份
if(this.getIsRun(year)){
return day[month+1];
}else{
return day1[month+1];
}
}
/**
*返回这个月的1号是星期几
*/

public int getWeek(int year,int month){
Date date=new Date();
date.setYear(year);
date.setMonth(month);
Calendar calendar=Calendar.getInstance();
calendar.setTime(date);
return calendar.get(calendar.DAY_OF_WEEK);
}

/**
*打印出来，嘎嘎
*/
public void showPrint(int year,int month){
int day=this.getDay(year,month);
int week=this.getWeek(year,month);
System.out.println("日\t一\t二\t三\t四\t五\t六\n");

for(int i=0;i<=week;i++){//
System.out.print (" \t");
}
for(int j=1;j<=day;j++){
if((j+week)%7==0){
System.out.println ();
}
System.out.print (j+"\t");

}
// System.out.println(week);
}

public static void main(String[] args){
Year y=new Year();
y.showPrint(2008,3);
}
}

⑶ java日历，求代码

importjava.util.Scanner;

/**
*java输入年,月得到日历
*
*@authoryoung
*
*/
publicclassPrintCalendar{
	publicstaticvoidmain(String[]args){
		Scannerinput=newScanner(System.in);
		System.out.print("Enterfullyear(eg:2001):");
		intyear=input.nextInt();
		System.out.print("Entermonthinnumber1between12:");
		intmonth=input.nextInt();
		printMonth(year,month);
	}

	publicstaticvoidprintMonth(intyear,intmonth){
		printMonthTitle(year,month);
		printMonthBody(year,month);
	}

	(intyear,intmonth){
		System.out.println(""+getMonthName(month)+""+year);
		System.out.println("______________________________");
		System.out.println("SunMonTueWedThuFriSat");
	}

	(intmonth){
		StringmonthName="";
		switch(month){
		case1:
			monthName="Fanuary";
			break;
		case2:
			monthName="January";
			break;
		case3:
			monthName="March";
			break;
		case4:
			monthName="April";
			break;
		case5:
			monthName="May";
			break;
		case6:
			monthName="June";
			break;
		case7:
			monthName="July";
			break;
		case8:
			monthName="August";
			break;
		case9:
			monthName="September";
			break;
		case10:
			monthName="October";
			break;
		case11:
			monthName="November";
			break;
		case12:
			monthName="December";
		}
		returnmonthName;
	}

	(intyear,intmonth){
		intstartDay=getStartDay(year,month);
		intnumberOfDaysInMonth=getNumberOfDaysInMonth(year,month);
		inti=0;

		for(i=0;i<startDay;i++){
			System.out.printf("%4s","");
		}
		for(i=1;i<=numberOfDaysInMonth;i++){
			System.out.printf("%4d",i);
			if((i+startDay)%7==0)
				System.out.println();
		}
		//System.out.println();
	}

	publicstaticintgetStartDay(intyear,intmonth){
		finalintSTART_DAY_FOR_JAN_1_1800=3;
		inttotalNumberOfDays=getTotalNumberOfDays(year,month);
		return(totalNumberOfDays+START_DAY_FOR_JAN_1_1800)%7;
	}

	(intyear,intmonth){
		inttotal=0;
		for(inti=1800;i<year;i++)
			if(isLeapYear(i))
				total=total+366;
			else
				total=total+365;
		for(inti=1;i<month;i++)
			total=total+getNumberOfDaysInMonth(year,i);
		returntotal;
	}

	//每个月天数
	(intyear,intmonth){
		if(month==1||month==3||month==5||month==7||month==8
				||month==10||month==12)
			return31;
		if(month==4||month==6||month==8||month==11)
			return30;
		if(month==2)
			returnisLeapYear(year)?29:28;
		return0;
	}

	//判断闰年
	publicstaticbooleanisLeapYear(intyear){
		returnyear%400==0||(year%4==0&&year%100!=0);
	}
}

⑷ JAVA编程输出月历

importjava.util.Calendar;
importjava.util.Scanner;

publicclassTest{
staticpublicvoidmain(String参数[]){
Calendarc=Calendar.getInstance();
Scannersc=newScanner(System.in);
System.out.println("请输入年份：");
intyear=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){
intwday=c.get(Calendar.DAY_OF_WEEK);
intmday=c.get(Calendar.DAY_OF_MONTH);
if(mday==1){
System.out.println("
日	一	二	三	四	五	六	第"+(c.get(Calendar.MONTH)+1)+"月");
System.out.println("---------------------------------------------------");
for(inti=0;i<wday-1;i++)System.out.print("	");
}
System.out.print(mday+"	");
if(wday==7)System.out.println();
c.add(Calendar.DAY_OF_YEAR,1);
}
}
}

⑸ 关于java中的月历

int month = Integer.parseInt(yearString); ===》用错变量了，正确的应该用“monthString ”

⑹ JAVA编写一个输出一个月月历的程序

输入本年的某个月后，屏幕输出这个月的月历，每星期一行，从星期日开始，到星期六结束。

import java.util.*;
public class Year{
/**
*判断是否为闰年
*/
public boolean getIsRun(int year){
if((year%4==0 && year %100 !=0)||(year%400==0)){
return true;
}
return false;
}
/**
*返回某年某月有多少天。
*/
public int getDay(int year ,int month){
int[] day={31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};//闰年月份
int[] day1={31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};//普通月份
if(this.getIsRun(year)){
return day[month+1];
}else{
return day1[month+1];
}
}
/**
*返回这个月的1号是星期几
*/
public int getWeek(int year,int month){
Date date=new Date();
date.setYear(year);
date.setMonth(month);
Calendar calendar=Calendar.getInstance();
calendar.setTime(date);
return calendar.get(calendar.DAY_OF_WEEK);
}
/**
*打印出来，嘎嘎
*/
public void showPrint(int year,int month){
int day=this.getDay(year,month);
int week=this.getWeek(year,month);
System.out.println("日\t一\t二\t三\t四\t五\t六\n");
for(int i=0;i<=week;i++){//
System.out.print (" \t");
}
for(int j=1;j<=day;j++){
if((j+week)%7==0){
System.out.println ();
}
System.out.print (j+"\t");
}
// System.out.println(week);
}
public static void main(String[] args){
Year y=new Year();
y.showPrint(2008,3);
}
}

⑺ java 月历（补充成能成功输出的）

是日历吧，直接拿系统的就是

⑻ 怎么用java编写一个指定的年月的日历

|package com;

import java.util.Calendar;
import java.util.Date;
import java.util.Scanner;

public class MyCalendar
{
public static void main(String[] args)
{
scanner = new Scanner(System.in);
String reg = "^(\\d+)[^\\d]+((0?[1-9])|(1[012]))$";
while(true)
{
System.out.println("输入年月(年和月用非数字隔开:如2015.1)(什么都不输入直接退出)");
String line = scanner.nextLine().trim();
if("".equals(line))
{
scanner.close();
break;
}
if(!line.matches(reg))
{
continue;
}
int year = Integer.parseInt(line.replaceAll(reg, "$1"));
int month = Integer.parseInt(line.replaceAll(reg, "$2"));
System.out.println("日\t一\t二\t三\t四\t五\t六");
Calendar calendar = Calendar.getInstance();
// 这个月的1号是星期几
calendar.set(year, month - 1, 1);
int day = calendar.get(Calendar.DAY_OF_WEEK);
int start = Calendar.SUNDAY;
calendar.add(Calendar.DATE, -day + start);
while(start < day)
{
System.out.print(calendar.get(Calendar.DATE) + "\t");
calendar.add(Calendar.DATE, 1);
start++;
}
calendar.set(year, month - 1, 1);
Date now = calendar.getTime();
calendar.set(year, month, 1);
Date next = calendar.getTime();
for(Date cur = now; cur.before(next);)
{
calendar.setTime(cur);
int x = calendar.get(Calendar.DATE);
String tmp = x < 10 ? "0" + x : x + "";
System.out.print(tmp + "\t");
if(calendar.get(Calendar.DAY_OF_WEEK) == Calendar.SATURDAY)
{
System.out.println();
}
calendar.add(Calendar.DATE, 1);
cur = calendar.getTime();
}
calendar.add(Calendar.DATE, -1);
int to = calendar.get(Calendar.DAY_OF_WEEK);
int end = Calendar.SATURDAY;
while(to < end)
{
calendar.add(Calendar.DATE, 1);
int x = calendar.get(Calendar.DATE);
String tmp = x < 10 ? "0" + x : x + "";
System.out.print(tmp + "\t");
to++;
}
System.out.println("\r\n");
}
}
}
