Java获得当前年月日并赋值给变量,主要是使用java 提供的工具类Calendar,Date来获取,如下代码:
package com.ob;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
public class DateTest {
public static void main(String[] args) throws ParseException {
Calendar now = Calendar.getInstance();
System.out.println("年: " + now.get(Calendar.YEAR));
System.out.println("月: " + (now.get(Calendar.MONTH) + 1) + "");
System.out.println("日: " + now.get(Calendar.DAY_OF_MONTH));
System.out.println("时: " + now.get(Calendar.HOUR_OF_DAY));
System.out.println("分: " + now.get(Calendar.MINUTE));
System.out.println("秒: " + now.get(Calendar.SECOND));
System.out.println("当前时间毫秒数:" + now.getTimeInMillis());
System.out.println(now.getTime());
Date d = new Date();
System.out.println(d);
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String dateNowStr = sdf.format(d);
System.out.println("格式化后的日期:" + dateNowStr);
String str = "2012-1-13 17:26:33"; //要跟上面sdf定义的格式一样
Date today = sdf.parse(str);
System.out.println("字符串转成日期:" + today);
}
}
输出结果:
年: 2012
月: 1
日: 13
时: 17
分: 28
秒: 19
当前时间毫秒数:1326446899902
Fri Jan 13 17:28:19 CST 2012
Fri Jan 13 17:28:19 CST 2012
格式化后的日期:2012-01-13 17:28:19
字符串转成日期:Fri Jan 13 17:26:33 CST 2012
Date date = new Date();
date.getYear();
date.getMonth();
date.getDay();
Date函数
date dt=new sysdate();应该有用吧
