java編寫日歷

我給你貼上我在java核心技術中看到的代碼吧,當然沒有輸入年份和月份,是按照當前時間創建的,寫有我寫的注釋,應該能看的懂

/*

* 2012年5月13日10:37:58

* 日歷程序

* Function:

* 顯示當前月份的日歷

* 總結

* 1. 0-11分別代表1-12月

* 1-7分別代表周日-周六

* 2. 使用GregorianCalendar對象的get方法（參數）獲取月，日，年等信息

* 3.

*/

import java.text.DateFormatSymbols;

import java.util.*;

public class CalendarTest {

public static void main(String[] args) {

//construct d as current date構造一個日期

GregorianCalendar d = new GregorianCalendar();

//獲取今天是這個月的第幾天

int today = d.get(Calendar.DAY_OF_MONTH); //Calendar.DAY_OF_MONTH作為參數調用，得到今天是這個月的第幾天

int month = d.get(Calendar.MONTH); //月份

d.set(Calendar.DAY_OF_MONTH, 1); //設置d的日期是本月的1號

int weekDay = d.get(Calendar.DAY_OF_WEEK); //獲取當天位于本星期的第幾天，也就確定了星期幾，值的范圍是1-7

int firstDayOfWeek = d.getFirstDayOfWeek(); //獲取一星期的第一天,我們得到的是Calendar.SUNDAY,因為我們一星期的第一天是周日

int indent = 0; //為了定位本月第一天，定義索引

while (weekDay != firstDayOfWeek) {

//注意，月份用0-11代表1-12月，為了清晰起見，使用常量代替，下面獲取月份得到的實際是當前月-1的值，所以我們要加1

//System.out.printf("當前星期的第%d天,位于當月的第%d天, 現在是%d月\n",

// weekDay, d.get(Calendar.DAY_OF_MONTH), d.get(Calendar.MONTH)+1); //Test Code

indent++;//縮進個數+1

d.add(Calendar.DAY_OF_MONTH, -1);//當前天數-1，如果現在是1號，則執行本條代碼后，時間變為上一個月最后一天

weekDay = d.get(Calendar.DAY_OF_WEEK); //重新獲取當天位于本星期的第幾天

}

String[] weekDayNames = new DateFormatSymbols().getShortWeekdays();//獲取簡短形式的星期字符串數組

//System.out.println(weekDayNames.length);getShortWeekdays()得到的數組的長度是8，下標為0的是沒有值1為星期日...7為星期六

//注釋代碼1

//Java核心技術的代碼

/*

do {

//System.out.printf("%4s", weekDayNames[weekDay]); //經過上面定義索引，weekDay代表的是本星期日

d.add(Calendar.DAY_OF_MONTH, 1); //天數加1

weekDay = d.get(Calendar.DAY_OF_WEEK); //重新獲得weekDay的值

} while (weekDay != firstDayOfWeek); //當循環完一個星期后，這里判斷不成立，退出循環

*/

//我寫的代碼，替換上面注釋代碼1

for (int i=1; iweekDayNames.length; i++)//打印星期標題

System.out.printf("%3s\t", weekDayNames[i]);//引號內是一個全角的空格，因為是中文版，不是書上英文環境,中文和空格對于不上,這里我們用\t解決

//System.out.printf("%3s　", weekDayNames[i]); //方式2

System.out.println();//換行

for (int i=1; i=indent; i++)//確定一星期的一天位置，利用上面indent

System.out.printf("\t");//如用方式2，則這里內容是四個全角空格

//實現輸出日期

d.set(Calendar.MONTH, month);
