I had a task to write simple game simulating two players picking up 1-3 matches one after another until the pile is gone. I managed to do it for computer choosing random value of matches but now I'd like to go further and allow humans to play the game. Here's what I already have : http://paste.pocoo.org/show/200660/

Class Player is a computer player, and PlayerMan should be human being. Problem is, that thread of PlayerMan should wait until proper value of matches is given but I cannot make it work this way. When I type the values it sometimes catches them and decrease amount of matches but that's not exactly what I was up to :) Logics is : I check the value of current player. If it corresponds to this of the thread currently active I use scanner to catch the amount of matches. Else I wait one second (I know it's kinda harsh solution, but I have no other idea how to do it).
Class Shared keeps the value of current player, and also amount of matches.

By the way, is there any way I can make Player and Shared attributes private instead of public and still make the code work ?

CONSOLE and INPUT-DIALOG is just for choosing way of inserting values.

class PlayerMan extends Player{

    static final int CONSOLE=0;
    static final int INPUT_DIALOG=1;
    private int input;

    public PlayerMan(String name, Shared data, int c){
    super(name, data);
    input = c;
    }

@Override
    public void run(){
        Scanner scanner = new Scanner(System.in);
        int n = 0;

        System.out.println("Matches on table: "+data.matchesAmount);
        System.out.println("which: "+data.which);
        System.out.println("number: "+number);

        while(data.matchesAmount != 0){
            if(number == data.which){

                System.out.println("Choose amount of matches (from 1 to 3): ");
                n = scanner.nextInt();

                if(data.matchesAmount == 1){
                    System.out.println("There's only 1 match left !");
                    while(n != 1){
                        n = scanner.nextInt();
                    }
                }
                else{
                    do{
                        n = scanner.nextInt();
                    }
                    while(n <= 1 && n >= 3);
                }

                data.matchesAmount = data.matchesAmount - n;
                System.out.println("                          "+
                        name+" takes "+n+" matches.");
                if(number != 0){
                    data.which = 0;
                }
                else{
                    data.which = 1;
                }
            }
            else{
                try {
                    Thread.sleep(1000);
                } catch(InterruptedException exc) {
                    System.out.println("End of thread.");
                    return;
                }
            }
            System.out.println("Matches on table: "+data.matchesAmount);
        }
        if(data.matchesAmount == 0){
            System.out.println("Winner is player: "+name);
            stop();
        }
    }
}
