Este codigo es del juego snake me pareció muy interesante, me lo paso un amigo y lo quiero compartir con ustedes, interesante lo del punto al azar en el cuadro, funciona en jcreator y en netbeans  







Esta clase se llama Snake

Esta esta es la clase principal para que funcione, Main.java
public class Main {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        new Snake();
    }
