I'm having trouble understanding why the third line below won't compile: Collection<? extends Number> c3; c3 = new Vector<Integer>(10); c3.add(new Integer(3));
Collection c is a Collection with a Bounded Wildcard that should be able to hold objects of subclasses of the abstract class Number, correct? Then, it would seem to me, that Integer, being a subclass of Number, should be allowable in that Collection. Yet, the compiler says, "... add(capture#781 of ? extends java.lang.Number) in java.util.Collection<capture#781 of ? extends java.lang.Number> cannot be applied to (java.lang.Integer)" I have no idea what that means.
