Characters in Tic Tac Toe

I am currently a week into learning Java, and I am doing a tic tac toe game. Almost everything is perfect, except for the fact that I don't know how to change 1's and 2's into X's and O's. My professor told us that we cannot change the main method. 0 represents a space, 1 represents an X, and 2 represents an O. 

public static void printBoard(int[][] board) {

    for (int i = 0; i < 3; i++) {
        for (int j = 0; j < 3; j++) {
            if (j == 2) {
                System.out.print(board[i][j] );
            } else {
                System.out.print(board[i][j] +  "  |");
            }
        }   
    }

}

One possibility is to create a method which converts a number to the character it represents, like below:

public static char toText(int num) {
    switch (num) {
        case 0: return ' ';
        case 1: return 'X';
        case 2: return 'O';
        default: return '?';
    }
}

And then you can use this method when printing your board. This would avoid having to change the way you internally represent your board:

for (int i = 0; i < 3; i++) {
    for (int j = 0; j < 3; j++) {
        if (j == 2) {
            System.out.print(toText(board[i][j]) );
        } else {
            System.out.print(toText(board[i][j]) +  "  |");
        }
}
