watch.java

是基于J2ME的一个模拟手机的界面可以实现手机收发短信基于客户端和服务器端的功能

package phone.function.secondWatch;
import javax.microedition.lcdui.Form;
import javax.microedition.lcdui.TextField;


class Watch extends Form implements Runnable {

	private TextField text;

	private boolean flag;

	private int count;

	public void run() {
		// TODO 自动生成方法存根
		while (true) {

				count++;
				
				try {
					
					int ms = count % 10;
					
					int s = count / 10 % 60;
					
					int m = count / 10 / 60 % 60;
					
					int h = count / 10 / 60 / 60;
					
					text.setString(h + ":" + m + ":" + s + ":" + ms);
					
					Thread.sleep(100);//休眠100秒
				} catch (InterruptedException e) {
					
					e.printStackTrace();
				}
			} else {
				
				break;
			}
		}
	}

	public void startWatch() {
