9.1.6 Checkerboard V1 Codehs | UPDATED |
Ensure your loops run while row < numRows , not <= , or you’ll hit an IndexOutOfBounds error.
If the of the row and column (row + col) is even , it gets one color.
Here is a standard way to write the program: 9.1.6 checkerboard v1 codehs
In CodeHS V1, you are often working with a Grid object. Remember that grid.set(row, col, value) is the standard syntax. If your specific assignment uses or Graphics , you would replace grid.set with putBall() or new Rect() , but the nested loop logic remains identical. Common Pitfalls
The secret to a checkerboard is simple math. To determine if a cell should be "colored" or "empty," you look at its row and column indices: Ensure your loops run while row If the
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. Key Components Explained 1. Nested For Loops
Creating a 9.1.6 Checkerboard V1 program in CodeHS requires a solid understanding of and 2D arrays (or grids). This exercise is a classic milestone in Java or JavaScript curriculum because it forces you to think about how coordinates interact. If your specific assignment uses or Graphics ,
Ensure you are using the correct color constants (e.g., Color.BLACK vs Color.black ) depending on your specific CodeHS library version.
