I was assigned a free-form Java coding assignment in my computer science class in which my group and I decided to make a Wheel of Fortune type game. I've been working on the GUI using JPaneland JFrame, which our online academy goes into some detail on, so I know most of the absolute basics. I managed to get a non-aesthetic but functioning box that displays individual player money and name in a class named playerPlate, as well as a button panel for all the buttons we will need at some point during the game in a class called buttonPanel.
When it came to making the letter/puzzle board where the puzzle is displayed on a 12-14-14-12 grid, I experienced a slew of problems. Here is my code for the letterBoard class which I'm using to try to make the puzzle board.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class letterBoard extends JPanel
implements ActionListener
{
private JTextField a1,a2,a3,a4,a5,a6,a7,a8,a9,a10,

Sorry about the sloppy code. First time posting and was having a bit pf trouble getting it to format correctly. When the above code is run through the wheelGUI class, it essentially creates 4 separate horizontal segments that are much smaller than I would like, editable, and not stacking correctly. I played around with different boxes, struts, and border layouts but could never get it to work properly. And while the code does compile and run (I'm aware of some consistency errors between the separate boxes, forgot to re-do that segment) it is extremely inefficient, as any changes must be done to ~52 different lines of code. I experimented with an iterate method I made:
public void iterate(JTextField[] foo)
{
board = foo;
for(int i=0; i<foo.length; i++)
{
foo[i] = new JTextField(" ");
}
}
However, this resulted in a NullPointerException error and did not properly instantiate the a1-52 variables to be used in the boxes. Any help I could get would be great. I apologize if my post and my code are a mess.
You should have an array of JTextFields and an array of Box or JPanel containers if that is what you need. Combine them in a for loop.
private JTextField[] fields = new JTextField[TEXT_FIELD_COUNT]; // const = 52
private Box[] boxes = new Box[SUIT_COUNT]; // suit count = 4
for (int i = 0; i < boxes.length; i++) {
boxes[i] = Box.createHorizontalBox();
for (int j = 0; j < TEXT_FIELD_COUNT/SUIT_COUNT; j++) {
int index = i * (TEXT_FIELD_COUNT / SUIT_COUNT) + j;
fields[index] = new JTextField(COLS); // COLS = some const, possibly 10
boxes[i].add(fields[index]);
// add your strut if desired
}
}
