Question

I have a programming assignment to create just a single sudoku puzzle.  I already have the puzzle I would like to use.  The problem I am at right now is I have created a toString method to display board, however, it has to be an int array and it is displaying zeros where I don't have initial values, which is what it is supposed to do.  My professor wants spaces displayed in the empty postions, she says it can be done with a simple if statement in the toString method, but I have been unable to come up with the proper code.  If someone can help me in accomplishing the displaying spaces issue I will rate ASAP.

Explanation / Answer

/* I have written the code for the toString() function whichincludes an If statement for displaying spaces instead of zeros */    public String toString()    {    String s="-------------------------- ";    for(int i=0; i
