Properly removing an Integer from a List

Question

Here\'s a nice pitfall I just encountered. Consider a list of integers:

List list = new ArrayList();
list.add(5);
list.add(6);         


        

Answer 1

I don't know about 'proper' way, but the way you suggested works just fine:

list.remove(int_parameter);

removes element at given position and

list.remove(Integer_parameter);

removes given object from the list.

It's because VM at first attempts to find method declared with exactly the same parameter type and only then tries autoboxing.
