What's the quickest way to remove an element from a Map by value in Java?
Currently I'm using:
DomainObj valueToRemove = new DomainObj();
String removalKey = null;
for (Map.Entry<String, DomainObj> entry : map.entrySet()) {
if (valueToRemove.equals(entry.getValue())) {
removalKey = entry.getKey();
break;
}
}
if (removalKey != null) {
map.remove(removalKey);
}
