Removing all items of a given value from a hashmap

Question

So I have a java hashmap like below:

hMap.put(\"1\", \"One\");
hMap.put(\"2\", \"Two\");
hMap.put(\"3\", \"Two\");

I would like to remove A

Answer 1

You can use while( hmap.values().remove("Two") ); since the remove call returns true if the collection was changed as a result of the call.
