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

A shorter usage of iterator is to use a values() iterator.

DomainObj valueToRemove = new DomainObj();
for (Iterator it = map.values().iterator(); it.hasNext();)) {
        if (valueToRemove.equals(it.next())) {
                it.remove();
                break;
        }
}
