I am trying to initialize a 2D array, in which the type of each element is char. So far, I can only initialize this array in the follow way. 

public class ticTacToe 
{
private char[][] table;

public ticTacToe()
{
    table[0][0] = '1';
    table[0][1] = '2';
    table[0][2] = '3';
    table[1][0] = '4';
    table[1][1] = '5';
    table[1][2] = '6';
    table[2][0] = '7';
    table[2][1] = '8';
    table[2][2] = '9';
}
}

I think if the array is 10*10, it is the trivial way. Is there any efficient way to do that?

Shorter way is do it as follows:

private char[][] table = {{'1', '2', '3'}, {'4', '5', '6'}, {'7', '8', '9'}};
