I have a List which is declared like this :
List<? extends Number> foo3 = new ArrayList<Integer>();
I tried to add 3 to foo3. However I get an error message like this:
The method add(capture#1-of ? extends Number) in the type List<capture#1-of ?
extends Number> is not applicable for the arguments (ExtendsNumber)
