9.1.6 Checkerboard V1 Codehs -

If the of the row and column (row + col) is even , it gets one color.

The is less about "drawing" and more about coordinate math . Once you master the (row + col) % 2 trick, you can generate patterns for much more complex grid-based games and visualizations. 9.1.6 checkerboard v1 codehs

Ensure your loops run while row < numRows , not <= , or you’ll hit an IndexOutOfBounds error. If the of the row and column (row

Ensure you are using the correct color constants (e.g., Color.BLACK vs Color.black ) depending on your specific CodeHS library version. Ensure your loops run while row Ensure you

You need to create a grid where cells alternate colors (usually black and white) to resemble a checkerboard. In CodeHS, this typically involves using the Grid class and the Color constants. The Logic: The "Odd/Even" Rule

public class Checkerboard extends ConsoleProgram { public void run() { // Define the size of the board int numRows = 8; int numCols = 8; // Create the grid Grid board = new Grid(numRows, numCols); // Use a nested loop to traverse every cell for (int row = 0; row < numRows; row++) { for (int col = 0; col < numCols; col++) { // Check if the sum of row and col is even if ((row + col) % 2 == 0) { // Set color (e.g., Black) board.set(row, col, Color.black); } else { // Set color (e.g., White/Empty) board.set(row, col, Color.white); } } } // Display the board System.out.println(board); } } Use code with caution.
