invalid method declaration; return type required

[michal5575]

Hi, I tryed to compile this:
package HelloWorld;

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

/**
* @author michal5575
*/
public class Midlet extends MIDlet {
private Display display = null;

private TextBox tbMainForm;

public MIDlet(){
tbMainForm = new TextBox("My First MIDlet","Hello World !",100,0);
}

public void startApp() {
if(display==null)
display = Display.getDisplay(this);
display.setCurrent(tbMainForm);
}

public void pauseApp() {
}

public void destroyApp(boolean unconditional) {
}
}


And i get this error:

invalid method declaration; return type required
public MIDlet(){

I don't really mess with micro edition, but don't you still need a public static void main(String args[])?

First things first, please use the [CODE] tags when posting code.

Take a look at the following block:

public MIDlet(){
tbMainForm = new TextBox("My First MIDlet","Hello World !",100,0);
}

Is that suppose to be a Constructor for the Midlet class? If so there is something wrong there... (Hint: 1st Line of the following Tutorials Providing Constructors for Your Classes)

Ok thx compilled successfuly. I used this code:

Test;

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

public class Midlet extends MIDlet implements CommandListener {

    private Display display;
    private TextBox textBox;
    private Command quitCommand;

    public void startApp() {
        display = Display.getDisplay(this);
        quitCommand = new Command("Quit", Command.SCREEN, 1);
        textBox = new TextBox("Hello World", "Looks different in Mobile", 40, 0);
        textBox.addCommand(quitCommand);
        textBox.setCommandListener(this);
        display.setCurrent(textBox);
    }

    public void pauseApp() {
    }

    public void destroyApp(boolean unconditional) {
    }

    public void commandAction(Command choice, Displayable displayable) {
        if (choice == quitCommand) {
            destroyApp(false);
            notifyDestroyed();
        }
    }
}
