clock002.java

J2ME的源码！我以前学习J2ME的源码哈！非常适合初学者

package clockDemo;

import javax.microedition.lcdui.Canvas;
import javax.microedition.lcdui.Graphics;

public class clock002 extends Canvas implements Runnable{
	private int time;

	public clock002(int time){
		this.time=time;
		Thread t=new Thread(this);
		t.start();
		
	}

	 protected void paint(Graphics g) {
		g.setColor(255, 255, 255);
		g.fillRect(0, 0, getWidth(), getHeight());
		int currentOffset = 0;
		g.translate(currentOffset, 0);		
		
		g.drawRect(155,0 ,getWidth(), getHeight());
		g.setColor(255,0,0);
		
		g.drawString("                                 "+time+"秒", 0, 0,g.TOP|g.LEFT);
	
	 }
	public void run() {
		while(time>=0){
			repaint();
			try {
				Thread.sleep(1000);
			} 
			catch (InterruptedException e) {
				e.printStackTrace();
			}
			time--;
		}
	}
