Why does the java.util.Set interface not provide a get(Object o) method? [closed]

Answer 1

I think your only solution, given some Set implementation, is to iterate over its elements to find one that is equals() -- then you have the actual object in the Set that matched.

K target = ...;
Set set = ...;
for (K element : set) {
  if (target.equals(element)) {
    return element;
  }
}
