Which Java Collection class allows generic elements to be stored in a sorted order?Question 3Answera.ArrayListb.PriorityQueuec.TreeMapd.HashSet
Solution
Para responder a la pregunta sobre qué clase de colección de Java permite almacenar elementos genéricos en un orden ordenado, vamos a analizar cada una de las opciones proporcionadas:
a. ArrayList: Esta clase permite almacenar elementos genéricos, pero no garantiza ningún orden específico de los elementos.
b. PriorityQueue: Esta clase almacena elementos en un orden basado en su prioridad, pero no necesariamente en un orden natural o definido por el usuario.
c. TreeMap: Esta clase almacena pares clave-valor en un orden ordenado según las claves. Utiliza un árbol rojo-negro para garantizar que las claves estén en orden ascendente.
d. HashSet: Esta clase almacena elementos únicos, pero no garantiza ningún orden específico de los elementos.
La opción correcta es c. TreeMap, ya que permite almacenar elementos genéricos en un orden ordenado basado en las claves.
