There are several ways to get current date and time in Java. Java programmers can use modern date and time API introduced in Java 8 (java.time), the classic, outdated API (java.util), and the third-party Joda library. The java.time package Thejava.timepackage contains the main API for...
Write a Java program to get the current time in New York.Sample Solution:Java Code:import java.util.*; public class Exercise5 { public static void main(String[] args) { Calendar calNewYork = Calendar.getInstance(); calNewYork.setTimeZone(TimeZone.getTimeZone("America/New_York")); System...
在Java里面,时间戳常用System.currentTimeMillis(),因为它可以方便地与Date/Calendar进行转 换,System.nanoTime到不是怎么常用(至少我没怎么用过)。刚才在学习Java的线程池中的 ScheduledThreadPoolExecutor时,看到里面很多地方都用到了它,于是好奇地看了下API。

一、System.currentTimeMillis(),它属于java.lang.System; 二、Calendar.getInstance().getTimeInMillis(),它属于java.util.Calendar; 三、new Date().getTime(),它属于java.util.Date; 下面是这三种方法各自运行100000所消耗的时间. package net.sahv.yrsy.test2;import java.util.Calendar;import java.util.Da...
System.currentTimeMillis();产生一个自1970年1月1日0时起到当前的毫秒。DK1.5之后java中的计时给出了更精确的方法：System.nanoTime()，输出的精度是纳秒级别 System.currentTime()，这个方法，它的精度是毫秒，返回值是从1970.1.1的零点开始到当前时间的毫秒数，理论上这个可以用来算当前的时间，...
