网上帮你找的跑马灯你可以使用 Timer 也可以使用线程间隔多少毫秒移动一段距离实现起来其实也不难
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();
}
}
}

}

显示时间:
<script language=javascript>
todayDate=new Date
date=todayDate.getDate()
month=todayDate.getMonth()+1
year=todayDate.getYear()
document.write("今天是")
document.write(" ")
document.write(year)
document.write("年")
document.write(month)
document.write("月")
document.write(date)
document.write("日")
document.write(" ")
if (todayDate.getDay()==0) document.write("星期日")
if (todayDate.getDay()==1) document.write("星期一")
if (todayDate.getDay()==2) document.write("星期二")
if (todayDate.getDay()==3) document.write("星期三")
if (todayDate.getDay()==4) document.write("星期四")
if (todayDate.getDay()==5) document.write("星期五")
if (todayDate.getDay()==6) document.write("星期六")
</script>
至于走马灯有好几种我不知道你需要的哪一种！
