You are given a Checkerboard class that extends GraphicsProgram . Your task is to write a program that draws a standard 8x8 checkerboard pattern. The board should have:
// Add the square to the canvas add(square);
Depending on the specific platform you are using, the assignment is typically implemented in either or JavaScript . 1. Java Implementation (CodeHS Style) 9.1.7 checkerboard v2 answers
By using (row + col) % 2 == 0 , we alternate 0s and 1s perfectly. 2. The Nested Loop Structure
Double-check if the top-left square (0,0) is supposed to be black, white, red, or active. Swap your if/else block conditions if the colors are inverted. You are given a Checkerboard class that extends
Because the sum of the coordinates alternates perfectly across both dimensions, checking if (row + col) % 2 == 0 guarantees a flawless checkerboard pattern regardless of grid size. ⚠️ Common Bugs and How to Fix Them
for (int row = 0; row < 8; row++) for (int col = 0; col < 8; col++) if ((row + col) % 2 == 0) board[row][col] = Color.RED; else board[row][col] = Color.BLACK; The Nested Loop Structure Double-check if the top-left
The "v2" in the title usually indicates that the standard solution using nested loops is required, but often with an added constraint (such as using ArrayList<ArrayList<Color>> instead of a primitive array, or using a specific helper class like CheckerboardV2 ).
