如何用JAVA寫日歷？

按照你的要求編寫的Java日歷驗證程序如下

UI.java

import?java.util.Scanner;

public?class?UI?{

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

public?static?int?askInt(String?s){

System.out.print(s);

return?sc.nextInt();

}

public?static?void?println(String?s){

System.out.println(s);

}

}

EE.java

public?class?EE?{

public?void?validateDateCore(){

int?year?=UI.askInt("Enter?the?year:?");

int?month=UI.askInt("Enter?the?month:?");

int?day=UI.askInt("Enter?the?day:?");

if(year??1){

UI.println("The?year?is?not?a?valid?number.");

return;

}

if(month1?||?month12){

UI.println("The?month?is?not?a?valid?number.");

return;

}

int?monthDay=0;

switch(month){

case?1:

case?3:

case?5:

case?7:

case?8:

case?10:

case?12:monthDay=31;break;

case?4:

case?6:

case?9:

case?11:monthDay=30;break;

case?2:

if((year%4==0??year%100!=0)?||?year%400==0){

monthDay=29;

}else{

monthDay=28;

}

break;

}

if(day1?||?daymonthDay){

UI.println("The?day?is?not?a?valid?number.");

return;

}else{

UI.println("It?is?"+day+"/"+month+"/"+year+".");

}

}

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

new?EE().validateDateCore();

}

}

運行結果

編寫 萬年歷java代碼例如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("輸入年月(年和月用非數字隔開:如2015.1)(什么都不輸入直接退出)");

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();

//?這個月的1號是星期幾

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();

}

}

}
