制作年历java代码 用java制作万年历

IT技术Calendar

高分求Java编写的万年历源代码,能够显示当前系统时间和日期查询 。import java.text.SimpleDateFormat;
import java.util.Calendar;
public class TestDate {
public static final String[] weeks = { "日", "一", "二", "三", "四", "五", "六" };
public static void main(String[] args) {
Calendar c = Calendar.getInstance();
c.set(Calendar.YEAR,2011);//2011年
c.set(Calendar.MONTH,0);//java中Calendar类，月从0开始，0代表一月
c.set(Calendar.DATE,1);//1号
int day = c.get(Calendar.DAY_OF_WEEK);//获致是本周的第几天地, 1代表星期天...7代表星期六
System.out.println(newSimpleDateFormat( "yyyy-MM-dd ").format(c.getTime()));
System.out.println("星期"weeks[day-1]);
}
}
用JAVA编写一个万年历importjava.io.*;
classputout{
publicvoidputout(intf,intx,inty){
inti;
inta[]=newint[40];
System.out.println("日一二三四五六" "" f "月");
for(i=0;ix;i)
{System.out.print("");}
for(i=x;ix y;i)
a[i]=i-x 1;
for(i=x;ix y;i)
{
if((i%7==0)(i0))
System.out.print("\n");
if(a[i]10)
System.out.print("" a[i]);
elseSystem.out.print("" a[i]);
}
System.out.println("\n");
}
}
classst{
publicstaticvoidmain(Stringargs[])throwsIOException{
putoutp=newputout();
intyear,mouth,y=1,t,i;
InputStreamReaderir;
BufferedReaderin;
ir=newInputStreamReader(System.in);
in=newBufferedReader(ir);
System.out.print("请输入一个年份：");
Strings=in.readLine();
year=Integer.parseInt(s);
if((year%4==0year0!=0)||(year@0==0))
mouth=1;
else
mouth=0;
y=year;
for(i=1;iyear;i)
{if((i%4==0i0!=0)||(i@0==0))
y;}
y=y%7;
for(i=1;i13;i){
switch(i){
case1:{p.putout(1,y,31);y=(y 31)%7;break;}
case2:{p.putout(2,y,28 mouth);y=(y 28 mouth)%7;break;}
case3:{p.putout(3,y,31);y=(y 31)%7;break;}
case4:{p.putout(4,y,30);y=(y 30)%7;break;}
case5:{p.putout(5,y,31);y=(y 31)%7;break;}
case6:{p.putout(6,y,30);y=(y 30)%7;break;}
case7:{p.putout(7,y,31);y=(y 31)%7;break;}
case8:{p.putout(8,y,31);y=(y 31)%7;break;}
case9:{p.putout(9,y,30);y=(y 30)%7;break;}
case10:{p.putout(10,y,31);y=(y 31)%7;break;}
case11:{p.putout(11,y,30);y=(y 30)%7;break;}
case12:{p.putout(12,y,31);y=(y 31)%7;break;}
}
}
}
}
编写 万年历java代码例如1900年一月一日是星期一 。import java.util.Calendar;
import java.util.Date;
import java.util.Scanner;
public class MyCalendar
{
public static void main(String[] args)
{
Scanner 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, -daystart);
while(startday)
{
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 = x10 ? "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(toend)
{
calendar.add(Calendar.DATE, 1);
int x = calendar.get(Calendar.DATE);
String tmp = x10 ? "0"x : x"";
System.out.print(tmp"\t");
to;
}
System.out.println();
}
}
}
如何 做JAVA 万年历import java.util.Calendar;
public class DateBean
{
private Calendar calendar = Calendar.getInstance();
public DateBean(int year, int month, int date){
calendar.set(year,month-1,date);
}
/*
*获取月份中制作年历java代码的第一个制作年历java代码的星期数
*1-7星期日到星期六
*@return int
*/
public int getFistWeek(){
int year = calendar.get(Calendar.YEAR);
int month = calendar.get(Calendar.MONTH);
calendar.set(year,month,1);
return calendar.get(Calendar.DAY_OF_WEEK);
}
/*
*当月最大天数
*@return int
*/
public int getMaxDate(){
int maxDate = calendar.getActualMaximum(Calendar.DATE);
return maxDate;
}
public void showCalendar(){
【制作年历java代码 用java制作万年历】System.out.println("日\t一\t二\t三\t四\t五\t六");
int min_week = getFistWeek();
int maxDate = getMaxDate();
int tempDate = 0;
//共有几周
int rowsCount = (maxDate-(7-min_week))/7;
if((maxDate-(7-min_week))%7 == 0){
rowsCount= 1;
}else{
rowsCount= 2;
}
for(int i=0; irowsCount; i){
int j = 0;
if(i==0){
j = min_week-1;
for(int o=0; omin_week-1; o){
System.out.print(" \t");
}
}
for(; j7; j){
if(tempDate=maxDate){
break;
}
tempDate;
System.out.print(tempDate "\t");
}
System.out.println();
}
}
public static void main(String[] args){
DateBean dateBean = new DateBean(2010,11,19);
dateBean.showCalendar();
}
}
JAVA万年历代码/*
题目:输出任意年份任意月份制作年历java代码的日历表(公元后)
思路:
1.已知1年1月1日是星期日,1 % 7 = 1 对应制作年历java代码的是星期日,2 % 7 = 2 对应的是星期一,以此类推;
2.计算当年以前所有天数 当年当月1号之前所有天数;
a.年份分平年闰年,平年365天,闰年366天;
b.闰年的判断方法year % 400 == 0 || (year % 100 != 0year % 4 == 0)若为真,则为闰年否则为平年;
c.定义平年/闰年数组,包含各月天数;
d.遍历数组求和,计算当年当月前总天数;
e.当年以前所有天数 当年当月前总天数 1即为1年1月1日到当年当月1日的总天数;
3.总天数对7取模,根据结果判断当月1号是星期几,输出空白区域;
4.输出当月日历表,逢星期六换行
