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<time.length; i++) {
      System.out.println(time[i]);
    }
  }

  static String[] getTime(String[] array) {
    String[] strArrays = new String[5];
    String str1 = "";
    String str2 = "";
    String str3 = "";
    String str4 = "";
    String str5 = "";

    for (int i=0; i<array.length; i++) {
      char[] chars = array[i].toCharArray();
      for (int a=0; a<chars.length; a++) {
        switch (chars[a]) {

            break;
        }
      }
      if(i < (array.length-1)) {

    return strArrays;
  }

}

以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持亿速云。

推荐阅读:
  1. 不用循环,不用递归,从1打印到100
  2. Java添加水印到Word文档
