AWT實現多線程

 一個簡單的多線程例子，由AWT實現，兩個按鈕，點擊第一個，開始自加，點擊第二個按鈕時結束，代碼如下。

 

import java.awt.*;
import java.awt.event.*;

class StopableFrame extends Frame implements Runnable, ActionListener{
	static long i = 0;
	static Label lab = new Label();
	Button but1 = new Button("Start");
	Button but2 = new Button("Stop");
	static boolean running = false;

	public void actionPerformed(ActionEvent e){
			if(e.getActionCommand().equals("Start")){
				new Thread(new StopableFrame(), "Start").start();
			}else{
				Thread t = new Thread(new StopableFrame(), "Stop");
				t.setPriority(10);
				t.start();
			}
	}
	
	public StopableFrame(){
		super();	
	}
	
	public void exec(){
			but1.addActionListener(this);
			but2.addActionListener(this);
			
			add(lab);
			add(but1);
			add(but2);
			
			setLayout(new GridLayout());
			setSize(300, 100);
			setVisible(true);
	}

	public StopableFrame(String name){
			super(name);
	}
	
	public void run(){
			if(Thread.currentThread().getName().equals("Start")){
				if(running){
					System.out.println("Process is running!!");
				}else{
					running = true;
					while(running){
						lab.setText(Long.toString(i++));
					}
				}
			}else{
					running = false;
					lab.setText(lab.getText() + "----Stoped !!!");
			}
	}
}

public class AWTThreadDemo{
	public static void main(String[] args){
		StopableFrame sf = new StopableFrame("Stopable Frame");
		sf.exec();
	}	
}
