Buenas. Estoy haciendo un programa en java para crear un rompecabezas con imagenes. He logrado cargar las imagenes y dividirla en las partes que el ususario quiera pero...estoy perdido al "barajar" las subimagenes (public void shuffle() lo he llamado) Aqui teneis el codigo por si podeis echarme una mano.
