Stream Vs. Iterator in entrySet of a Map - Java 8

Question

To my understanding, the following code should have print true, since both Stream and Iterator are pointing to the first element.

Answer 1

No both entry1 and entry2 are has same value but they are not pointing the same object because the each time you get the Map.Entry object it create new one.
Look at the below code :

import java.util.Collections;
import java.util.HashMap;
import java.util.Map;
import java.util.Set;

public class Test1 {

    public static void main(String[] args) {
        final HashMap map = new HashMap<>();
        map.put("A", "B");
        final Set> set = Collections.unmodifiableMap(map).entrySet();
        Map.Entry entry1 = set.iterator().next();
        Map.Entry entry2 = set.stream().findFirst().get();
        System.out.println("entry1 : " + System.identityHashCode(entry1));
        System.out.println("entry2 : " + System.identityHashCode(entry2));
        for (int i = 0; i < 5; i++) {
            System.out.println("directly for set " + i + " : " + System.identityHashCode(set.stream().findFirst().get()));
        }
    }
}

The output is :

entry1 : 1283928880
entry2 : 295530567
directly for set 0 : 2003749087
directly for set 1 : 1324119927
directly for set 2 : 990368553
directly for set 3 : 1096979270
directly for set 4 : 1078694789

System.identityHashCode() will give hash code.
