Compare string array values

Hi Experts

I am designing a MUD game and wanted to include a dance feature, something similar to dance dance revolution but for the keyboard. Unfortunately you cannot use keypress in a telnet session so I opted for an array of strings that are printed to the screen and the user has to type them back.

This is my code

public void dance(){

                        String input = null;
                        String[] word = new String[20];
                        String[] moves = {"up ","up "};
                        
                        for(int i=0; i< moves.length; i++){
                              Game.server.out(moves[i]);
                              try {
                                    input = Game.server.ir.readLine();
                                    word = input.split(" ");
                                    String out = moves[i];
                                    for(int j=0; j<word.length; j++){
                                    String in = word[j];
                                    if(in.equalsIgnoreCase(out)){
                                          Game.server.out("Cool");
                                    }
                                    }
                              } catch (IOException e) {
                                    // TODO Auto-generated catch block
                                    e.printStackTrace();
                              }
                        try{
                        Thread.sleep(1000);
                        }
                        catch(Exception e)
                        {
                        System.out.println(e);
                        }
                        }                  
      }

It prints the array to the screen and accepts the incoming text but does not seem to compare the values tried all sorts can’t get it to work would appreciate any help.

What I would like is the word to print to the out stream the user enters it into the in stream and if it is right the out stream prints cool or something like that and then prints the next item in the array.

Thanks

Clive

Did you set auto-flush on true, while getting the outputstream?

You could also do:
Game.server.out("Cool");
Game.server.flush();

In case of auto-flushing you probably have sth like:
new PrintWriter(this.server.getOutputStream());

change that into:
new PrintWriter(this.server.getOutputStream(), true);

Already had it flushing as you suggested in your second comment mark, I have also implemented flush() as advised in your first comment unfortunately it has no effect.

Does the code look correct? I haven't made any obvious errors?

Thanks for trying

Maybe you typed the wrong word? :-)
If you could give me some code which I can easily compile and try then I can have a better look at it, for now as i see it, it looks like good code.

PS: wasn't kidding about the "did you type the correct word", i see a space after the "up", is that correct?

I was hoping to put mulitiple arrays and have one choose at random is that easy to do? would i use math.random?

If it's tricky i will repost it for more points.

Thanks again

That's easy i guess, you can use a 2 dimensional array or a list of arrays.
I'm not sure what you want to randomize, so let's say you have a fixed number of "random sequences", then you can put them all inside an array and pick a random element with:

int index = (int) Math.floor(Math.random()*somearray.length)
...somearray[index]...

I was thinking of having multiple arrays such as

 String[] moves1 = {"up ","up "};
 String[] moves2 = {"up ","up "};
 String[] moves3 = {"up ","up "};

and then picking one of the arrays at random each time the code is executed.

Is your way a bit more elegant?

Thanks

ADSLMarkCommented:
your way is not possible, since you cannot dynamically bind a number to a variable name like:

String[] randomMoves = (moves + Math.random());

So you need sth like;

String[][] moves= { {"up","left"}
                            ,  {"down","up"}
                            ,  {"up","right"} };

Now you can access each array with just an integer like:
moves[1] will get the array: {"down","up"}
