    Default Counting cells

    Hi guys, I have a program that prints a rectangle when you type the width and height as command line arguments. I have got it to print out the rectangle but What i am trying to do is make it count each cell and see if its odd/even. If its even, i want it to add another row and column to make it odd So i can make a hole in the middle of the rectangle i.e. miss a cell out:

    int width = Integer.parseInt(args[0]);
    int height = Integer.parseInt(args[1]);
    int count;
    for (int row = 1; row <= height; row++)
    {
    for (int column = 1; column <= width; column++)
    System.out.print("[_]");
    // end the line.
    System.out.println();

    Any help?

    Kind regards

    Shyam

    Default Re: Counting cells

    throw this in there before the for loops
    		if(width%2==0) width++;
    		if(height%2==0) height++;
