# Java Program to Determine the Color of a Chess Square

## Introduction

In this post, we will learn how to write a Java program that can determine the color of a chess square from the given coordinates.

As a chess player, you may have come across situations where you need to determine the color of a particular square on the chess board.

For example, you may need to check if a certain piece is attacking an enemy piece on a square of a different color.

Before we start writing the code, let’s first understand how the chess board is laid out. A chess board has 8 rows and 8 columns, and the squares are alternately colored white and black.

The top left square is white, and the bottom right square is also white. The rest of the squares alternate in color as you move from left to right and top to bottom.

Now we have understood the layout of the chess board, let’s write the Java code to determine the color of a particular square.

## Java Program to Determine the Color of a Chess Square

First, we will create a class called `ChessSquareColor` and define a method called `getSquareColor()` that takes in two arguments – the row and column coordinates of the square.

```public class ChessSquareColor {
public static String getSquareColor(int row, int col) {
// code to determine the color of the square goes here
}
}```

Next, we will use a simple mathematical formula to determine the color of the square.

If the sum of the row and column coordinates is even, then the square is white, otherwise it is black.

```public static String getSquareColor(int row, int col) {
if ((row + col) % 2 == 0) {
return "white";
} else {
return "black";
}
}```

That’s it! We have successfully written a Java program to determine the color of a chess square.

To test the program, we can call the `getSquareColor()` method and pass in different row and column coordinates. Here is an example:

```public static void main(String[] args) {
System.out.println(ChessSquareColor.getSquareColor(0, 0));  // prints "white"
System.out.println(ChessSquareColor.getSquareColor(0, 1));  // prints "black"
System.out.println(ChessSquareColor.getSquareColor(1, 0));  // prints "black"
System.out.println(ChessSquareColor.getSquareColor(1, 1));  // prints "white"
}
```

I hope this tutorial was helpful in teaching you how to determine the color of a chess square in Java.

You can use this program in your own chess-related projects or simply as a fun way to learn about chess and programming.
