In this issue, Xiaobian will bring you about Java dynamics how to display the current date and time. The article is rich in content and analyzes and narrates from a professional perspective. After reading this article, I hope you can gain something.

Java dynamically displays the date and time of the current system; as shown in the figure:

package com.xin.test; import java.awt.Color; import java.awt.Font; import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import java.text.SimpleDateFormat;import java.util.Date; import javax.swing.JLabel;import javax.swing.Timer;import javax.swing.JFrame; public class NowTime extends JFrame { private static final long serialVersionUID = 43068033267723920L; //Add JLabel public NowTime() { JLabel time = new JLabel(); time.setForeground (Color.BLUE); time.setBounds (30, 0, 900, 130); time.setFont (new Font("Microsoft Yahei", Font.BOLD, 80)); this.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE); this.setLayout(null); this.setTitle ("now time"); this.setBounds (500, 200, 930, 200); this.setVisible(true); this.add(time); this.setTimer(time);} //Set Timer 1000ms to implement an action is actually a thread private void setTimer (JLabel time) { final JLabel varTime = time; Timer timeAction = new Timer (100, new ActionListener() { public void actionPerformed (ActionEvent e) { long timeMillis = System.currentTimeMillis(); //convert date display format SimpleDateFormat df = new SimpleDateFormat ("y-MM-dd HH:mm:ss"); varTime.setText(df.format(new Date(timemillis))); } }); timeAction.start(); }/Method of operation public static void main(String[] args) { new NowTime(); } }

The above is a small series for everyone to share Java dynamics how to display the current date and time, if there is a similar doubt, may wish to refer to the above analysis to understand. If you want to know more about it, please pay attention to the industry information channel.
