Percorer HashMap


Recommended Posts

como eu percorro o meu hashmap até encontrar o CPF 111.111.222-33 com o método getCpf.

ao achar, imprime "encontrei"

Se não achar, imprime "não encontrei"

com a collection array list eu consegui.

for(Pessoa p: nomes) {
 if (p.getCpf() == "111.222.333-44") {
 System.out.println("não ncontrei");


como faço com hashmap? segue código abaixo

package exercicio5;

import java.util.Collection;
import java.util.HashMap;
import java.util.Iterator;

public class TestePessoaMapa {

public static void main(String[] args) {

   HashMap<String, Pessoa> map = new HashMap<String, Pessoa>();
   map.put("1", new Pessoa("Mauricio", "111.111.222-33", 23));
   map.put("2", new Pessoa("Geana", "511.411.322-34", 27));
   map.put("3", new Pessoa("Fabricio", "516.416.326-36", 21));

boolean found = false;
Iterator<Pessoa> iterator = map.values().iterator();
while (iterator.hasNext() && !found) {
 Pessoa p = iterator.next();
 if (p.getCpf() == "111.222.333-44")
   found = true;

if (found)
 System.out.println("Não encontrei");
