Checkerboard

Write a program that takes a positive integer ?n and displays an ?n x n checkerboard. For example, when n? = 5, the program displays a 5 x 5 checkerboard. Make sure that the adjacent squares differ in color regardless of whether n? is odd or even. Write the program in such a way that it works for different values of n by changing only one line in your code. Hint: Use un-editable TextField objects in a GridPane, and use CSS to set background colors.
