File -> New -> select j2me --> j2me Midlet suite -> click Next

Give the project name as HelloworldMobileApp and click Next

It create the HelloworldMidlet class and inherit the some methods.

Now add these following code.

import javax.microedition.lcdui.*;

import javax.microedition.midlet.MIDlet;

import javax.microedition.midlet.MIDletStateChangeException;

public class HelloworldMidlet extends MIDlet {

private Form form;

private Display display;

public HelloworldMidlet() {

form = new Form("My First J2ME App");

String msg = "Hello World";

form.append(msg);

display = Display.getDisplay(this);

display.setCurrent(form);

}

protected void destroyApp(boolean arg0) throws MIDletStateChangeException {

notifyDestroyed();

}

protected void pauseApp() {

// TODO Auto-generated method stub

}

protected void startApp() throws MIDletStateChangeException {

// TODO Auto-generated method stub

}

}

We did finish coding now. But in order to run your app you have to do some configuration.

Right click the project --> Run as --> Run Configuration

Click Browse and select the project.
