I do not understand this.
I get no compiler complaints with this code:
Collection<?> c = new ArrayList<Integer>
(10); // This code works
c = new ArrayList<Long>
(10); // This code
works
c = new ArrayList<String>
(10); // This code
works
But when i try to add an Integer to the ArrayList I get complaints
form the compiler:
Collection<?> c = new ArrayList<Integer>
(10); // This code works
c.add
(10);
//
Complains ???????????????
c = new ArrayList<Long>
(10); // This code
works
c = new ArrayList<String>
(10); // Thiscode
works
When i try this:
Collection <Integer> c = new ArrayList<Integer>(10);
c.add
(10);
//
NO PROBLEM
I thought i really understood this section up until this...
Can anyone tell me why the code will not work?
Thanks, Gary
