Java获取时间打印到控制台代码实例

Java获取时间打印到控制台代码实例

这篇文章主要介绍了java获取时间打印到控制台代码实例,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

面试时有一道面试题：要求获取当时时间，并像电子手表那样打印到控制台。

import java.text.SimpleDateFormat;

import java.time.LocalTime;

import java.util.Date;

/**

* 打印时间到控制台

*/

public class ConsoleTime {

public static void main(String[] args) {

// LocalTime now = LocalTime.now();

// System.out.println(now);

// System.out.println(now.getHour() + " " + now.getMinute() + " " + now.getSecond());

Date date = new Date();

//yyyy-MM-dd

SimpleDateFormat format = new SimpleDateFormat("HH:mm:ss");//设置日期格式

String str = format.format(date);

System.out.println("现在时间：" + str);

String[] time = getTime(str.split(":"));

for (int i=0; i

System.out.println(time[i]);
