I am using NAME_1 17. Is there any way to refactor the following code to combine the three NAME_1 statements into a single statement?

    HashMap<ContactPreference, ContactData> tempMap =
        new HashMap<>(newMandatoryContactPrefsAndOptInNContactsMap);

    tempMap.putAll(newMonMandatoryContactPrefsAndOptInNContactsMap);

    return tempMap;
 Use words with all capital letters to highlight key points, but make sure that words with all capital letters appear less than 16 times
