El método restante de la capacidad() de DelayQueue siempre devuelve Integer.MAX_VALUE porque DelayQueue no tiene restricciones de capacidad. Eso significa que, independientemente del tamaño de DelayQueue, devuelve el mismo resultado, es decir, Integer.MAX_VALUE.
Sintaxis:
public int remainingCapacity ()
Valor devuelto: la función devuelve Integer.MAX_VALUE .
Excepción: No hay excepciones presentes.
Los siguientes programas ilustran el método DelayQueue.remainingCapacity():
