The basics would be an actor to display the text -- a basic Actor subclass class is:

public class SimpleActor extends greenfoot.Actor {}

-- and the following in your World subclass:

// a field to hold the actor
private Actor resetActor;

// a game over method with the following to apply the reset actor
GreenfootImage resetText = new GreenfootImage("Click here to play again", 48, Color.BLACK, new Color(0, 0, 0, 0));
GreenfootImage resetImage = new GreenfootImage(resetText.getWidth()+30, resetText.getWidth()+20);
resetImage.setColor(Color.RED);
resetImage.fill();
resetImage.setColor(Color.LIGHT_GRAY);
resetImg.fillRect(3, 2, resetImage.getWidth()-6, resetImage.getHeight()-4);
resetImage.drawImage(resetText, 15, 10);
resetActor = new SimpleActor();
resetActor.setImage(resetImage);
addObject(resetActor, getWidth()/2, getHeight()/2);

// and finally, in act method
if (resetActor != null && Greenfoot.mouseClicked(resetActor)) Greenfoot.setWorld(new MyWorld());

All the imaging from line 6 through to line 11 is not needed, but makes it look better (without which line 13 can set resetText as the image for resetActor).

seems that it is defining itself, a little earlier above.

I think it obvious that it should have been resetImage.

ok i tried doing the code differently but it doesn't work

public class Text extends Actor
{    
    public void act() 
    {
        GreenfootImage resetText = new GreenfootImage("Play again", 48, Color.BLACK, new Color(0, 0, 0, 0));        
        if(Greenfoot.mouseClicked(resetText))
        {
            Greenfoot.setWorld(new Start());
        }
    } 
}

public class GameOver extends World
{
    public GameOver()
    {    
        // Create a new world with 600x400 cells with a cell size of 1x1 pixels.
        super(900, 600, 1); 
        
        Add();
    }
    
    public void Add()
    {
        Text text = new Text();
        addObject(text,450,450);
    }
}

Try this:

public class Text extends Actor
{
    public Text()
    {
        GreenfootImage resetText = new GreenfootImage("Play again", 48, Color.BLACK, new Color(0, 0, 0, 0));
        setImage(resetText);
    }
    
    public void act()
    {
        if (Greenfoot.mouseClicked(this)) Greenfoot.setWorld(new Start());
    }
}
