实验的时候要求做一个走马灯程序，写完顺便发上来填补下博客的空白，日后有空还会发更多自己编写的程序，让大家指教指教……

package clock;

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

import java.util.Calendar;

import java.util.Date;

import java.text.*;

public class removingLight extends JFrame {

public removingLight() {

Font font1 = new Font("幼圆", Font.BOLD, 16);

Calendar cal = Calendar.getInstance();

SimpleDateFormat formatter = new SimpleDateFormat(

"EEEE,MMMMdd日，yyyy年 HH:mm:ss");

String mDateTime = formatter.format(cal.getTime());

MovingMessagePanel messagePanel = new MovingMessagePanel(mDateTime);

messagePanel.setFont(font1);

messagePanel.setBackground(Color.BLACK);

messagePanel.setForeground(Color.PINK);

add(messagePanel);

}

public static void main(String[] args) {

removingLight frame = new removingLight();

JLabel label = new JLabel("开始调试时间：5月5日     结束调试时间：5月6日");

label.setBackground(Color.black);

frame.setTitle("软件1班   XXX 3107006757");

frame.setLocationRelativeTo(null);

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setSize(320, 120);

frame.add(label, BorderLayout.SOUTH);

frame.setVisible(true);

}

static class MovingMessagePanel extends JPanel {

private String message = " ";

private int xCoordinate = 0;

private int yCoordinate = 40;

public MovingMessagePanel(String message) {

this.message = message;

Timer timer = new Timer(100, new TimerListener());

timer.start();

}

public void paintComponent(Graphics g) {

super.paintComponent(g);

if (xCoordinate > getWidth()) {

xCoordinate = -100;

}

xCoordinate += 5;

g.drawString(message, xCoordinate, yCoordinate);

}

class TimerListener implements ActionListener {

public void actionPerformed(ActionEvent e) {

repaint();

}

}

}

}

实验的效果：
