Java – extract values from HashMap

I try to learn and understand through the work of HashMap So I created this HashMap to store some values that will give output when displayed using the iterator

1=2
 2=3
 3=4

wait. I use iterator The next () function gets this output Now what I really doubt is that, due to the type of the value returned by the iterator object, if I only need to extract the right value of the above equivalent, what is the function? Something like a string Is there any way I can get the results

2
 3
 4

Any help would be appreciated Thank you in advance

Solution

I'll use something like that

Map<Integer,Integer> map = new HashMap<>();

for(int value: map.values())
   System.out.println(value);
