Sudoku Java Question?

Ok heres my code so far.

public class Sudoku {

private int N = 3; //sets N to 3

private int[][]board; // creates the board.

private int square = N*N;

public Sudoku() //constructor sets all values to 0

{

board = new int [N*N][N*N]; //sets board size

for (int x=0; x< square; x++){

for(int y=0; y< square; y++){

board [x][y]=0; // sets all elements to 0

}

}

}

public int getSquare(int i, int x){ // Gets the value of board[i][x]

if(i >=0 && i< square && x>=0 && x<square)

return board[i][x];

else

return 0;

}

public void setSquare(int i, int x, int val) // Sets board[i][j] = a value between 1 - 9.

{

board[i][x] = val;

}

public void show()

{

for (int i=0; i< square; i++)

{

if (i%N == 0 && i > 0)

System.out.println("------+------+------");

for(int x=0; x< square; x++){

if (board [i][x] == 0)

System.out.print(" .");

else

System.out.print(" " + board [i][x]);

if ((x+1)%N == 0 && x < square -1)

System.out.print("|");

}

System.out.println();

}

}

public static void main (String []Args)

{

Sudoku s = new Sudoku();

s.show();

}

}

now what i need to know is after I set all the numbers = to 0, how can I put in an array of numbers in its place? I dont need it to be user interactive, I can create the array and pick numbers that work, I just need to know how to implement it?

I asked this question before but every1 just gives me examples of full sudoku games and Im a beginner so I dont understand it. Could someone please tell me how to set every element of the board[][] 2d array with numbers?
