Chapter 15 - Programming question 5 "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 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 in your code. Hint: Use un-editable TextField objects in a GridPane, and use CSS to set background colors.

*Only use chapter materials for this program

*Use javaFX components for this program

Can someone please help me with this?
