extracting values from HashMap

hashmap, iterator, java

Solution

I would use something like

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

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

Problem

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.
