Also, in the toString() if you want to clean it up a bit and not use all those if-else statements, you could use two instances of TreeMap or two parallell arrays (I think that's what they're called) and the code would be a bit neater. It was just easier for me to copy and paste, though, so that's why I'm using the if-else statements in case you were wondering.

Whoa - sorry to back up on you guys, but I have to interject here. An ArrayList will take primitive values. I pasted the code in from his original post to find out what the problem was and the only issue I had was with the cs1.Keyboard class. I created a Scanner

(Toggle Plain Text)

Scanner input = new Scanner( System.in );

and replaced

(Toggle Plain Text)

value = Keyboard.readInt();

with

(Toggle Plain Text)

value = input.nextInt();

and it worked fine. I'm not sure where your error was coming from.

ArrayList's will take ints, but they are implicitly converted to Integers. This is called autoboxing. Anytime you pass a priitive value to an ArrayList, it will box it into the corresponding object pair (int-Integer, float-Float, boolean-Boolean, etc). If you want to specify a particular type, you can do so (in jdk 1.5+) by using generics. So an ArrayList that takes int or Integer values would look like this:

(Toggle Plain Text)

ArralyList<Integer> list = new ArrayList<Integer>();

Wen you use generics, the parameter between the angle brackets does have to be a non-priitive, but you can still pass in primitive types (they'll be auto-boxed).

Or you could just use

(Toggle Plain Text)

list.isEmpty()

You might also consider creating enum types for the rank of a card and the suit of a card.

Heh. Didn't know that. I stand corrected.

Sorry if my ways seem unusual its just I have not been taught how to use "Scanners" thats all.

No, I'm sure your class is fine. I just didn't have access to it, so I used Scanner as a quick keyboard input method.

From now on I will put a link to the site that you can get that at as soon as i find that site again
