Java获取时间年、月、日的方法

本文实例讲述了java获取时间年、月、日的方法。分享给大家供大家参考。具体实现方法如下：

package com.date.demo; 
import java.text.parseexception; 
import java.text.simpledateformat; 
import java.util.calendar; 
import java.util.date; 
public class datedemo { 
  public static void main(string args[]) { 
    system.out.println("---------------获取当前时间的年月日-----------------"); 
    getmonthday(); 
    system.out.println("---------------获取自定义时间的年月日-----------------"); 
    getmonthday2set(); 
  } 
  /** 
   * 获取自定义时间的年月日 
   */ 
  private static void getmonthday2set() { 
    string datestr = "2013-11-10 18:45:39"; 
    simpledateformat sdf = new simpledateformat("yyyy-mm-dd hh:mm:ss"); 
    calendar cal = calendar.getinstance(); 
    date dt = null; 
    try { 
      dt = sdf.parse(datestr); 
      cal.settime(dt); 
    } catch (parseexception e) { 
      // todo auto-generated catch block 
      e.printstacktrace(); 
    } 
    int year = cal.get(calendar.year); 
    int month = cal.get(calendar.month) + 1; 
    int day = cal.get(calendar.day_of_month); 
    int hour = cal.get(calendar.hour_of_day); 
    int minute = cal.get(calendar.minute); 
    int second = cal.get(calendar.second); 
    system.out.println("===年===" + year); 
    system.out.println("===月===" + month); 
    system.out.println("===日===" + day); 
    system.out.println("===时===" + hour); 
    system.out.println("===分===" + minute); 
    system.out.println("===秒===" + second); 
  } 
  /** 
   * 获取当前时间的年月日 
   */ 
  private static void getmonthday() { 
    calendar cal = calendar.getinstance(); 
    int year = cal.get(calendar.year); 
    int month = cal.get(calendar.month) + 1; 
    int day = cal.get(calendar.day_of_month); 
    int hour = cal.get(calendar.hour_of_day); 
    int minute = cal.get(calendar.minute); 
    int second = cal.get(calendar.second); 
    system.out.println("===年===" + year); 
    system.out.println("===月===" + month); 
    system.out.println("===日===" + day); 
    system.out.println("===时===" + hour); 
    system.out.println("===分===" + minute); 
    system.out.println("===秒===" + second); 
  } 
}
