Consider the following alternate remove() implementation:
public boolean remove(E obj) {
int index = firstIndex(obj);
if(index != -1)
return remove(index);
return false;
}
Would this code work on every List implementation? (e.g. ArrayList, LinkedList, etc.)

Question

Consider the following alternate remove() implementation:

public boolean remove(E obj) {

int index = firstIndex(obj);

if(index != -1)

return remove(index);

return false;

}

Would this code work on every List implementation? (e.g. ArrayList, LinkedList, etc.)

Accepted Answer

Yes, it would work for all Lists that implement the List ADT.

Answer

No, this would only work in an ArrayList since we have direct access to elements.

Answer

No, this would only work in a LinkedList.

Answer

No, this code would run successfully, but its not removing the correct element.
