I am making a game like that of in snake.class 
import greenfoot.*;  // (World, Actor, GreenfootImage, Greenfoot and MouseInfo etc)

public class Snake extends Actor
{
    public void act() 
    {
        MouseInfo pointer = Greenfoot.getMouseInfo();
        if(pointer != null)
        {
            int mouseX = pointer.getX();
            int mouseY = pointer.getY();
            turnTowards(mouseX, mouseY);
        }
        move(5);
        if(isTouching(Food.class))
        {
            removeTouching(Food.class);
            PryHabitat.counter.add(1);

        }
    }    
}
and notice 
PryHabitat.counter.add(1);
line. it adds a score, but when it gets value`33` it should stop and show text "Congrats" but the point is:What should we write for "getValue()"???

 I know that to import 
"import java.awt.Color"
First. ignore telling that.

First, the counter should not be static. You would use '<counterReference>.getValue() == 33' in an if statement. Your counterReference is PryHabitat.counter but that is not really a good idea... As an alternative, you could put the condition into the add method of the counter. Why would you want to import the java.awt.Color class?

If you are using the newest Greenfoot version, then there is greenfoot.Color which replaces java.awt.Color. Anyways, I didn't only write this last line.
