Re: Object wrappers and Lists in ObjectiveC and Java

[Nick Collier]

If you mean putting primitive "int"s into a Java collection, you do need
to create their Object equivalents. So,

Vector v = new Vector();
int i = 2;
v.add(new Integer(2));

and to get it out:

Integer anInt = (Integer)v.get(0);
int j = anInt.intValue();
