Write a program that takes a positive integer n and displays an n x n checkerboard. For example, when n = 5, the program displays as in the image below. Make sure that 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 of your code. Hint: USe the uneditable TextField objects in a GridPane , and use CSS to set the background colors.
