java中用什么来记录年月日信息阿？

Question

不知道你要问什么。
有没有看过java.util.Date 和 java.util.Calendar?

Answer 1

date中的setYear()和getYear()都禁用了，我又只知道年月日，怎么办？

Answer 2

import  java.util.date
实例化一个date对像A
A.getYear()
A.getMonth()
A.getDay()

Answer 3

int getYear() 
          Deprecated. As of JDK version 1.1, replaced by Calendar.get(Calendar.YEAR) - 1900. 而且，java.sql.Timestamp是继承java.util.Date的，应该也可以用getYear()方法。import java.sql.Timestamp;public class Demo{
public static void main(String []args)
{
Timestamp dt = Timestamp.valueOf("2003-8-11 00:00:00.0");
System.out.println(dt.toString());

int year = dt.getYear();
System.out.println(year);
}
}但结果是：
2003-8-11 00:00:00.0
103为什么？

Answer 4

Date d = new Date();
        Calendar calendar = new GregorianCalendar();
        calendar.setTime(d);    
        System.out.println("ERA: " + calendar.get(Calendar.ERA));
        System.out.println("YEAR: " + calendar.get(Calendar.YEAR));
        System.out.println("MONTH: " + (1 + calendar.get(Calendar.MONTH)));        System.out.println("WEEK_OF_YEAR: " + calendar.get(Calendar.WEEK_OF_YEAR));
        System.out.println("WEEK_OF_MONTH: " + calendar.get(Calendar.WEEK_OF_MONTH));
        System.out.println("DATE: " + calendar.get(Calendar.DATE));
        System.out.println("DAY_OF_MONTH: " + calendar.get(Calendar.DAY_OF_MONTH));
        System.out.println("DAY_OF_YEAR: " + calendar.get(Calendar.DAY_OF_YEAR));
        System.out.println("DAY_OF_WEEK: " + calendar.get(Calendar.DAY_OF_WEEK));
        System.out.println("DAY_OF_WEEK_IN_MONTH: "
                        + calendar.get(Calendar.DAY_OF_WEEK_IN_MONTH));
        System.out.println("AM_PM: " + calendar.get(Calendar.AM_PM));
        System.out.println("HOUR: " + calendar.get(Calendar.HOUR));
        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));
        System.out.println("ZONE_OFFSET: "
                        + (calendar.get(Calendar.ZONE_OFFSET)/(60*60*1000)));
        System.out.println("DST_OFFSET: "
                        + (calendar.get(Calendar.DST_OFFSET)/(60*60*1000)));
