How to access a list element within a Hashmap?

Question

I am saving data into a Hashmap , with a String being the key and a List being the value. How would I be able to access a specific element in the value List ?

For example :

I want to access the element at index 5 within the values List .

Thanks in advance:)

You can iterate over keys by calling map.entrySet().

for (Map.Entry<String, List<String>> entry : map.entrySet()) {
    List<String> list = entry.getValue();
    
    // get value
    list.get(5);
}
