Añadir elementos a un ArrayList ya existente
Publicado por Fran (13 intervenciones) el 05/05/2021 02:12:41
Buenas.
Previo al trozo de codigo que voy a pegar, se añaden equipos y jueces. Lo que intento ahora es recorrer la arraylist de jueces para puntuar los equipos. Eso me sale hasta ahora (mas o menos).
Lo que me falla es la parte de realizar el ranking con esas puntuaciones. Es como si los elementos de puntos se añadieran al final de la arraylist en lugar de relacionados al equipo que se ha puntuado.
Gracias por vuestra ayuda!!
