Estava estudando e me deparei com a seguinte questao
Given:
11. public class Person {
12. private name;
13. public Person(String name) {
14. this.name = name;
15. }
16. public int hashCode() {
17. return 420;
18. }
19. }
Which is true?
A. The time to find the value from HashMap with a Person key depends
on the size of the map.
B. Deleting a Person key from a HashMap will delete all map entries for
all keys of type Person.
C. Inserting a second Person object into a HashSet will cause the first
Person object to be removed as a duplicate.
D. The time to determine whether a Person object is contained in a
HashSet is constant and does NOT depend on the size of the map.
Answer: A
Teria como alguem me explicar pq a resposta daria A?
pq alem de faltar especificar o tipo da variavel “name”(o que geraria erro de compilação)
a resposta nao dependeria do tamanho do nome pois eu to retornando 420 de qualquer forma.
Att,Marcos.
