Can't seem to figure this out...

I just created an account to ask the users of this forum if they could figure out my problem.

So, let's get right into it. I'm coding a client for Minecraft.

First, I declared an ArrayList like so:

Code:

---

public ArrayList<Bind> binds = new ArrayList<Bind>();

---

Then, when the user types into a console "bind <key> <cmd>[;<cmd>]" it adds a Bind to the array list, like so:

Code:

---

if(s.startsWith("bind")) {
        String[] args = s.split(" ");
        if(args.length > 2) {
                        try {
                                        String key = args[1].toUpperCase();
                                        int kCode = Keyboard.getKeyIndex(key);
                                       
                                        String cmd = "";
                                        for(int i=2; i<args.length; i++) {
                                                cmd += args[i] + " ";
                                        }
                                       
                                        boolean exists = false;
                                        if(kCode != Keyboard.KEY_NONE) {
                                                for(int i=0; i<binds.size(); i++) {
                                                        if(kCode == binds.get(i).keyCode) {
                                                                binds.set(i, new Bind(kCode, cmd));
                                                                mc.thePlayer.addChatMessage("Overwrote a bind!");
                                                                exists = true;
                                                                break;
                                                        }
                                                }
                                }
                                       
                                        if(!exists) {
                                                binds.add(new Bind(kCode, cmd));
                                                mc.thePlayer.addChatMessage(binds.get(binds.size() - 1).bind);
                                        }
                                } catch (Exception e) {        }
        } else {
                mc.thePlayer.addChatMessage("Syntax: bind <key> <cmd>[;<cmd>]");
        }
}

All works fine, until I add another bind. After I add another it just sets both keys to do what the second one was set to do and I'm not sure. :|

Sorry for the double post as I'm sure that's against the rules, but I figured out how to fix it. For some reason .set doesn't work as I assumed it does so I just removed the bind then added another.

Not at all, if you figure out the answer for yourself please do tell us as it saves us wasting time trying to solve something you've already solved.

If you're not sure what a method does read the API docs. For 'ArrayList.set(..)' the docs say

"Replaces the element at the specified position in this list with the specified element."

And I can confirm it's worked this way every time I've used it.
