main.java

基于j2me实现的HelloWorld

import javax.microedition.lcdui.Display;
import javax.microedition.midlet.MIDlet;
import javax.microedition.midlet.MIDletStateChangeException;

public class Main extends MIDlet {
	static Main instance;

	public Main() {
		// TODO Auto-generated constructor stub
		instance = this;
		dis = Display.getDisplay(instance);
	}
	Display dis;
	HelloWorld helloword;

	protected void destroyApp(boolean unconditional) {
		// TODO Auto-generated method stub
		if (instance != null)
			instance.notifyDestroyed();
	}

	protected void pauseApp() {
		// TODO Auto-generated method stub

	}

	protected void startApp() throws MIDletStateChangeException {
		// TODO Auto-generated method stub
		if (helloword == null)
			helloword = new HelloWorld(this);
	}
