Tic Tac Toe Board - Java

Question

I was trying to write a code for Tic Tac Toe Game. I wrote the following code to display the board of the game but something is wrong and it isn't displaying the required output. Could you please help me figure out where the mistake is?

Here:

0 represents blank ,

1 represents X and

2 represents O .

public class Trying
{
    public static void main(String[] args) {

    int board[][] = {{1,0,2},
                    {0,1,0},
                    {0,2,0}};

        for(int row = 0; row<3; row++)
        {
            for(int col = 0; col<3; col++)
            {
                printCell(board[row][col]);
                if(col<2)
                {
                    System.out.print(" | ");
                }
            }
            System.out.println("\n------------");
        }
    }

    public static void printCell(int content){
        switch(content){
            case 0: System.out.print(" ");
            case 1: System.out.print("X");
            case 2: System.out.print("O");
        }
    }
}

Output:

Answer 1

You forgot your break; s in your switch statement, try:

public static void printCell(int content){
    switch(content){
        case 0: System.out.print(" ");
            break;
        case 1: System.out.print("X");
            break;
        case 2: System.out.print("O");
            break;
    }
}

Read here for why we need break;

Answer 2

You need a break (and maybe a tabulator character to get the same distance in the signs)

public static void main(String[] args) {

    int board[][] = { { 1, 0, 2 }, { 0, 1, 0 }, { 0, 2, 0 } };

    for (int row = 0; row < 3; row++) {
        for (int col = 0; col < 3; col++) {
            printCell(board[row][col]);
            if (col < 2) {
                System.out.print("|");
            }
        }
    }
    System.out.println("\n--------------------------------------------");
}

public static void printCell(int content) {
    switch (content) {
        case 0:
            System.out.print("\t \t");
            break;
        case 1:
            System.out.print("\tX\t");
            break;
        case 2:
            System.out.print("\tO\t");
            break;
    }
}
