Retrieve values from hashmap (.values()) [duplicate]

Question

I would be pleasure if you can suggest. Could you suggest how properlly I can retriev all values from hashmap. In such simplee example:

    Map<String, Values> someMap = ....;
    List<Values> valuesFromMap = (List<Values>) someMap.values();

After that I've got that, Java couldn't cast to java.util.List

Thank you in advanced.

someMap.values() returns Collection. If you need to convert into List than do that as follows:

 List<Values> valuesFromMap = new ArrayList<>(someMap.values());
