Question

What\'s the quickest way to remove an element from a Map by value in Java?

Currently I\'m using:

    DomainObj valueToRemove = new DomainObj();
    S         


        

Answer 1

map.values().removeAll(Collections.singleton(null));

reference to How to filter "Null" values from HashMap?, we can do following for java 8:

map.values().removeIf(valueToRemove::equals);
