JavaRedux: Integer methods + List::remove + NoSuchElementException

[FliegendeWurst]

Intended Change

The Integer class is a bit useless without providing at least valueOf and intValue, so I added specifications for those methods. And the field value to store the int value.

The List::remove method to remove elements by index is useful to have.

The NoSuchElementException class is required to implement iterators.

[FliegendeWurst]

I would like to add a test that checks the below is provable, how would I go about that?

    /*@ public normal_behavior
      @ ensures \result;
      @ assignable \nothing;
      @*/
    static boolean testRemove() {
        List list = new ArrayList();
        list.add("a");
        list.add("b");
        list.add("c");
        Object removed = list.remove(0);
        return removed == "a" && list.get(0) == "b" && list.get(1) == "c";
    }
