extracting values from HashMap

Question

I was trying to learn and make understanding out of the working of a HashMap. So i created this hashmap to store certain values which upon displaying using an Iterator gives me outputs as

 1=2
 2=3
 3=4

and so on. This output i obtain using the Iterator.next() function. Now what my actual doubt is that since the type of this value returned in of an Iterator Object, if i need to extract only the right hand side values of the above equalities, is there any function for that? Something like a substring. Is there any way i could just get results as

 2
 3
 4

Any help will be appreciated. thanks in advance.

Answer 1

I would use something like

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

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