Page 1038, Java textbook 3rd Ed. (by Tony Gaddis)

// Use the following imports

import javafx.application.Application;

import javafx.scene.Scene;

import javafx.scene.control.TextField;

import javafx.scene.layout.GridPane;

import javafx.stage.Stage;

// Create a GridPane object and pass it to the scene later as the root object.

// Create a TextField object with a number in it for each grid of ‘rows by columns’ matrix of

// grids

// Use the following code segment for locating the row and the column of each grid.

        for (int k = 1; k <= size*size; k++)

        {

           int row = (k-1) / size;

           int col = (k-1) % size;

            // add your code

            // ………

            gridPane.add(tField, col, row);

        }

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TextField;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;

public class MyClass {
public static void main(String args[]) {
//Gridplane object
GridPane gridPane = new GridPane();
for (int k = 1; k <= size*size; k++)
{
int row = (k-1) / size;
int col = (k-1) % size;
// add your code
// ………
  
//Textfeild object
TextField tField = new TextField();
gridPane.add(tField, col, row);
}
