What is inside this for statement? How else could we have written the for-statement?
for(Card card : c){
deckArrayList.remove(card);
this.remove(card);
this.repaint();
}
I *think* your first question is about the stuff between
the first set of parentheses (although the precise meaning of
"inside" isn't clear to me). Perhaps you are surprised not to
see the usual three pieces separated by semicolons, now known
as the "basic for statement" (JLS 14.14.1).
Depending on what `c' is (you've kept that information to
yourself, for reasons that again are not clear), there are at
least two other ways to write the loop:
- If `c' is an `Iterable<Card>', we can write
for (Iterator<Card> it = c.iterator(); it.hasNext(); ) {
Card card = it.next();
// remainder of loop body
}
- If `c' is an array of `Card', we can write
for (int i = 0; i < c.length; ++i) {
Card card = c[i];
// remainder of loop body
}
(Actually, the second rewrite isn't *quite* equivalent to the
original, but it's equivalent unless the loop body makes `c' refer
to a different array while executing.)
Any Java textbook written in the last decade or thereabouts
will explain this.
... and this is the *last* answer you will get from me until
and unless you start using better Subject lines!

Except on *.announce or *.advocacy, that is.
But there is neither comp.lang.java.announce nor comp.databases.announce,
at least not from individual.de.
So? That doesn't mean it's on topic in any of the newsgroups it was
posted to.
