Can someone help me what I am doing wrong with this code?

[Jainam Patel]

Hey Guys, I am making a TicTacToe Game in Java and I am having someone difficulty figuring out what I am doing Wrong.

1. I made a tic tic toe board which look something like this.
   Hide Copy Code
   System.out.println(" | | );
   System.out.println( 0 | 1 | 2 );
   System.out.println( | | );
   System.out.println( -------------------------------);
   System.out.println( | | );
   System.out.println( 3 | 4 | 5 );
   System.out.println( | | );
   System.out.println( -------------------------------);
   System.out.println( | | );
   System.out.println( 6 | 7 | 8 );
   System.out.println( | | );

2. I asked the user for a number between 0-8 and the number they choose will be Replaced by X.

Say they choose number 5. This is how it will look like.

Hide Copy Code
System.out.println(" | | );
System.out.println( 0 | 1 | 2 );
System.out.println( | | );
System.out.println( -------------------------------);
System.out.println( | | );
System.out.println( 3 | 4 | X );
System.out.println( | | );
System.out.println( -------------------------------);
System.out.println( | | );
System.out.println( 6 | 7 | 8 );
System.out.println( | | );

3. I don't know how to create a loop which will keep asking the user for a number until it reaches to all the 8 numbers. Also, how do I check if the number is taken or not.

IT WILL BE GREAT IF YOU CAN HELP ME.

Why are you constantly posting same question in two different forums? I have already posted the answer to your problem on your question, Can someone help me what I am doing wrong with this code?[^]. Read that thread.

public class tictok {

private int OO = 1;
private int XX = -1;
public int arr\[\] = new int\[10\];

public int getArrPos(int i,int j)
{
    if (i==1) {
        return j == 4?1:j==15?2:j==26?3:-1;
    }

    return -1;
}

public void printMap() {
    for(int i=0;i<11;i++) {
        for(int j=0;j<32;j++) {
            if (i==3 || i==7) {
                System.out.print("-");
                continue;
            }
            if (j==10 || j==21) {
                System.out.print("|");
                continue;
            }
            if(getArrPos(i, j)!=-1){
                if (arr\[getArrPos(i, j)\]== OO) {
                    System.out.print("O");
                }else if (arr\[getArrPos(i, j)\]==XX) {
                    System.out.print("X");
                }else  {
                    System.out.print(getArrPos(i, j));
                }
                continue;
            }
            System.out.print(" ");
        }
        System.out.println();
    }
}

public void play(int n,boolean isO)
{
    if (n>9) {
        System.out.println("silly B");
        return;
    }
    arr\[n\]= isO?1:-1;
}


public static void main(String\[\] args) {
    tictok tt = new tictok();
    tt.play(8, true);
    tt.play(6, false);
    tt.printMap();

}

}

is it useful？
