復制代碼 代碼如下:

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);
}
}
