JAVA计时器(秒表)程序代码

1、Java计时器（秒表）功能：能实现计时，暂停，清零，记录功能。如下图：程序运行状态：源代码：import javax.swing.*;import java.awt.*;import java.awt.event.*;public class Test public static void main(String args)new window("计时器");class window extends JFrameint ON=0,i=0,j=0,k=0,count=0,num=1,R=0;JButton button1,button2,button3,button4,but

2、ton5;JTextField file1,file2,file3;JTextArea file;FlowLayout flow;String a,b,c;window(String name)file1=new JTextField(2);file2=new JTextField(2);file3=new JTextField(2);file1.setEditable(false);file2.setEditable(false);file3.setEditable(false);file=new JTextArea(10,8);file.setEditable(false);button1

3、=new JButton("开始");button2=new JButton("暂停");button3=new JButton("清零");button4=new JButton("记录");button5=new JButton("清空记录");flow=new FlowLayout();flow.setAlignment(FlowLayout.LEFT);flow.setHgap(20);flow.setVgap(10);setTitle(name);setSize(210,400);se

4、tLayout(flow);add(file1);add(new JLabel(":");add(file2);add(new JLabel(":");add(file3);add(button1);add(button2);add(button3);add(button4);add(button5);add(file);setVisible(true);setDefaultCloseOperation(EXIT_ON_CLOSE);file1.setText("0");file2.setText("0");fil

5、e3.setText("0");validate();button1.addActionListener(new ActionListener() public void actionPerformed(ActionEvent e) ON=1; /开始，暂停控制开关); /开始按钮button2.addActionListener(new ActionListener() public void actionPerformed(ActionEvent e)ON=0;); /暂停按钮button3.addActionListener(new ActionListener()

6、public void actionPerformed(ActionEvent e)R=1; /清零控制开关); /清零按钮button4.addActionListener(new ActionListener() public void actionPerformed(ActionEvent e)count=1; /记录控制开关a=String.valueOf(i);b=String.valueOf(j);c=String.valueOf(k);); /记录按钮button5.addActionListener(new ActionListener() public void action

7、Performed(ActionEvent e)file.setText("");num=1;); /清除记录按钮while(true)validate();if(ON=1) /开始或暂停判断file1.setText(String.valueOf(i);file2.setText(String.valueOf(j);file3.setText(String.valueOf(k);if(k=99)k=-1;j+;if(j=60)k=0;j=0;i+;if(i=24)i=0;j=0;k=0;tryThread.sleep(10);catch(Exception e)k+;if(count=1)/记录判断file.append(String.valueOf(num);file.append(". ");file.append(a);file.append(":");file.append(b);file.append(":");file.append(c);file.append("n");num+;count=0
