复制代码 代码如下:

package test.remote.tools.combine;

import java.text.SimpleDateFormat;

import java.util.Calendar;

import java.util.Date;

import java.util.GregorianCalendar;

public class TestOutDate

{

public static void main(String[] args)

{

//method 1

Calendar nowtime = new GregorianCalendar();

String strDateTime="["+String.format("%04d", nowtime.get(Calendar.YEAR))+"/"+

String.format("%02d", nowtime.get(Calendar.MONTH))+"/" +

String.format("%02d", nowtime.get(Calendar.DATE))+" " +

String.format("%02d", nowtime.get(Calendar.HOUR))+":" +

String.format("%02d", nowtime.get(Calendar.MINUTE))+":" +

String.format("%02d", nowtime.get(Calendar.SECOND))+"." +

String.format("%03d", nowtime.get(Calendar.MILLISECOND))+"]";

System.out.println(strDateTime);

//method 2

String msg="";

Date date = new Date();

SimpleDateFormat sdf = new SimpleDateFormat("YYYY/MM/dd HH:mm:ss.SSS");

msg+="["+sdf.format(date)+"]";

System.out.println(msg);

}

}

运行结果：
