java中弄出系统时间的几个方法

Date d = new Date();
String date = d.toLocaleString(); //获取当前日期，然后你可以自己对这个字符串进行处理。或者用d.getDate();等方法，单独取它的日期等等。

Timestamp time = new Timestamp(System.currentTimeMillis());
System.out.println(time.toString());

import java.lang.System;
import java.util.Date;

     public class Date{
       
           public static void main(String args[]){
       
                    Date today=new Date();

                    System.out.println("Today's date(Locale) is:"

                         +today.toLocaleString());


       }
}

Calendar cal=Calendar.getInstance();
                Date now=new Date();
                cal.setTime(now);

import java.util.*;
import java.text.*;
public class DateDemo{
        public static void main(String[] args){
                SimpleDateFormat dateFormatter =new SimpleDateFormat("yyyy-MM-dd-HH:mm:ss");
                GregorianCalendar gc=new GregorianCalendar();
                System.out.println(dateFormatter.format(gc.getTime()));
        }
}
