ok so here is the problem i was trying to get my mouse to be able to click "TRY AGAIN" and then to restart the game but it didnt work so im using keys instead now but what would be a good restart code? like when you press "x" it would just restart the game heres what my section looks like i put in a lil spot for it if u know what to put. 
 public void getEaten()
    {
        //  Code for sound (if you want)
        //  Code to remove crab (if you want)
        CrabWorld gw = (CrabWorld) getWorld();
        ScoreBoard scoreboard = new ScoreBoard(counter.getValue());   
        gw.addObject(scoreboard, 273, 302);
        gw.repaint();
        while(!Greenfoot.isKeyDown("right")){}
        //insert program restart here
        
        Greenfoot.stop();
    }

The easiest way is to put code in the world class that looks to see if a crab is in the world and if not remove all objects a re-prepare the world, if the user clicks a 'Try again' button. 
// In the world act() method
if (getObjects(Crab.class) == null)
{
    if (getObjects(Button.class) == null) addObject(new Button(), [centerX], [centerY])
    return;
}
Then in the button class check for mouseClick, and when clicked, call the world prepare method, reset variables, and remove button (you could have a seperate method for initializing variables in the world class and call it).

This would mean lines 8 through 12 in the code above should be replaced by 
gw.removeObject(this);
return;

Yeah, I put them in brackets so, I hoped, you would know to replace them with getWidth() / 2 and getHeight() / 2.

No, it is in the Greenfoot API. Just use 
public void act()
    if (Greenfoot.mouseClicked(this))
    {
        CrabWorld gw = (CrabWorld) getWorld();
        gw.addObject(new Crab(), [spawnX], [spawnY]); // replace what is in square brackets
        gw.prepare();
        gw.resetVariables(); // you might have to create this
        gw.removeObject(this);
    }
}

The button class can be fairly simple 
import greenfoot.*;
import java.awt.Color;

public class Button extends Actor
{
    public Button()
    {
        setImage(new GreenfootImage(" Try again ", 30, Color.BLACK, Color.RED));
    }

    public void act() // as above
    //  etc.
}
