Creating a LIST

[Anna Husten]

Hey guys,

I am coding a simple List but I do not know how to kill this compiler error:

 
import javax.microedition.lcdui.*;
import javax.microedition.midlet.MIDlet;

public class ListMIDlet extends MIDlet {
	private List hauptliste;
	private Display display;
	
	public static final Command CMD_BACK = new Command("Zurück",Command.BACK,1);
	 private static final Command CMD_ENDE = new Command("Ende", Command.EXIT, 1);
	
	protected void startApp() {
		if (display == null) { // beim ersten Aufruf
			display = Display.getDisplay(this);
			String[] optionen = { "Red","Blue","Green" };
			hauptliste = new List("IMPLICIT-Liste", Choice.IMPLICIT, optionen);
			hauptliste.addCommand(CMD_ENDE);
			
			hauptliste.setCommandListener(new CommandListener() {
					public void commandAction(Command c, Displayable d) {
						List list = (List) d;
						if (list == hauptliste) {
							if(c == CMD_ENDE) 
								notifyDestroyed();
							
							
						}
					}
			});
			
			display.setCurrent(hauptliste);
		}
	}
	
	protected void pauseApp() {
	}
	
	protected void destroyApp(boolean b) {
	}
}

Shouldn't

hauptliste = new List("IMPLICIT-Liste", Choice.IMPLICIT, optionen);

be

hauptliste = new List("IMPLICIT-Liste", Choice.IMPLICIT, optionen, null);
