If you have to use a HashMap, then the simplest way is probabably just to loop through the Map looking for the maximum

Entry maxEntry = null;

for(Entry entry : uniqueNames.entrySet()) {
    if (maxEntry == null || entry.getValue() > maxEntry.getValue()) {
        maxEntry = entry;
    }
}
// maxEntry should now contain the maximum,
