Java中解释一些日历类(CalendarClass)中的重要方法?

Calendar类(理解)

Calendar类是采用手工的方式取得日期,可以通过此类精确到毫秒,此类的定义如下:

public abstract class Calendar extends Object

implements Serializable, Cloneable, ComparableCalendar

这个类本身是一个抽象类,抽象类要想实例化肯定使用子类:GregorianCalendar

package org.lxh.api.datedemo;

import java.util.Calendar;

import java.util.GregorianCalendar;

public class CalendarDemo {

public static void main(String[] args) {

Calendar calendar = new GregorianCalendar();

System.out.println("YEAR: " + calendar.get(Calendar.YEAR));

System.out.println("MONTH: " + (calendar.get(Calendar.MONTH) + 1));

System.out.println("DATE: " + calendar.get(Calendar.DATE));

System.out

.println("HOUR_OF_DAY: " + calendar.get(Calendar.HOUR_OF_DAY));

System.out.println("MINUTE: " + calendar.get(Calendar.MINUTE));

System.out.println("SECOND: " + calendar.get(Calendar.SECOND));

System.out

.println("MILLISECOND: " + calendar.get(Calendar.MILLISECOND));

}

}

但是现在有一个问题,如果每次取时间都按照这种方式取的话,那么得累死,那么能不能设计一个类,可以通过此

类直接取得时间呢,例如:现在给出了如下的一个接口:

package org.lxh.api.datedemo;

public interface DateTime {

/**

*取得日期

* @return 日期的字符串,例如:2009-12-22

*/

public String getDate() ;

/**

*取得日期时间

* @return 日期时间的字符串,例如:2009-12-22 11:06:23.345

*/

public String getDateTime() ;

/**

*取得时间戳

* @return 返回时间戳的字符串,例如:20091222110623345

*/

public String getTimeStamp() ;

}

前面需要补0的问题需要注意,例如:01。

package org.lxh.api.datedemo;

import java.util.Calendar;

import java.util.GregorianCalendar;

public class DateTimeImpl implements DateTime {

private Calendar calendar;

public DateTimeImpl() {

this.calendar = new GregorianCalendar();

}

public String getDate() {

StringBuffer buf = new StringBuffer();

buf.append(calendar.get(Calendar.YEAR)).append("-");

buf.append(this.addZero((calendar.get(Calendar.MONTH) + 1), 2)).append("-");

buf.append(this.addZero(calendar.get(Calendar.DATE), 2));

return buf.toString();

}

public String getDateTime() {

StringBuffer buf = new StringBuffer();

buf.append(calendar.get(Calendar.YEAR)).append("-");

buf.append(this.addZero((calendar.get(Calendar.MONTH) + 1), 2)).append("-");

buf.append(this.addZero(calendar.get(Calendar.DATE), 2)).append(" ");

buf.append(this.addZero(calendar.get(Calendar.HOUR_OF_DAY), 2)).append(":") ;

buf.append(this.addZero(calendar.get(Calendar.MINUTE), 2)).append(":") ;

buf.append(this.addZero(calendar.get(Calendar.SECOND), 2)).append(".") ;

buf.append(this.addZero(calendar.get(Calendar.MILLISECOND), 3)) ;

return buf.toString();

}

@Override

public String getTimeStamp() {

StringBuffer buf = new StringBuffer();

buf.append(calendar.get(Calendar.YEAR));

buf.append(this.addZero((calendar.get(Calendar.MONTH) + 1), 2));

buf.append(this.addZero(calendar.get(Calendar.DATE), 2));

buf.append(this.addZero(calendar.get(Calendar.HOUR_OF_DAY), 2));

buf.append(this.addZero(calendar.get(Calendar.MINUTE), 2)) ;

buf.append(this.addZero(calendar.get(Calendar.SECOND), 2)) ;

buf.append(this.addZero(calendar.get(Calendar.MILLISECOND), 3)) ;

return buf.toString();

}

private String addZero(int num, int len) {

StringBuffer buf = new StringBuffer();

buf.append(num);

while (buf.length() len) {

buf.insert(0, 0);

}

return buf.toString();

}

}

JAVA编写日历

SWING和线程的技术。。至于日期类,估计你应该知道吧,如果不知道赶紧查API吧。你可以百度一下,想飞社区,在资源里 JAVA版日期控件。说明文档+源码都有,你可以参考一下。最终成型如下图

求!JAVA日历!!

import java.util.Calendar;

class CalendarList{

int year,month;

int dayNum,i,num,count=0;

Calendar objCalendar;

int[] arrDayNum=;

CalendarList(){

objCalendar=Calendar.getInstance();

this.year=objCalendar.get(Calendar.YEAR);

this.month=objCalendar.get(Calendar.MONTH)+1; //要+1

}

CalendarList(String args0,String args1){

this.year=Integer.parseInt(args1);

this.month=Integer.parseInt(args0);

objCalendar=Calendar.getInstance();//这里没有get

objCalendar.set(Calendar.YEAR,year);//set是这样用的

objCalendar.set(Calendar.MONTH,month-1);

}

void display(){

System.out.println("\t\t\t"+year+"年"+month+"月");

System.out.println("日 一 二 三 四 五 六"); //每个空3个空格

num=objCalendar.get(Calendar.DAY_OF_WEEK);

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

arrDayNum[1]+=1;

}

for (i=1;i=12;i++){

if (i==month){

dayNum=arrDayNum[i-1];

break;

}

}

for(i=1;i=num;i++){

System.out.print(" ");//5个空格

count++;

}

for (i=1;i=dayNum;i++){

System.out.print(i10?" "+i+" ":i+" "); //自己改了下 ,空格数:1,3,3

count++;

if(count==7){

System.out.println();

count=0;

}

}

System.out.println ();

}

}

public class MainClass {

public static void main(String[] args) {

CalendarList objCalendar=new CalendarList();

CalendarList objCalendar1=new CalendarList("11","2007");

objCalendar.display();

objCalendar1.display();

}

}
