Plz help me to fix the code below

Question

ArrayList <Integer> list = new ArrayList <Integer>();
for(int i = 0; i < 6; i++) {
list.add(i);
}
int x = 0;
Iterator <Integer> it = list.iterator ();
while (it.HasNext()) {
x+ = it.next();
}
System.out.println (x);

Answer 1

import java.util.ArrayList;
import java.util.Iterator;

it.hasNext() -> not HasNext
x += it.next() -> x+ = gives an error

Answer 2

Please look at the code. Hope it helps you 😉
