Hello,
I had to make this program and it is all working except it is not writting to the file. Can you help me out?

Here is the code:

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;

/**
 * Program that allows user to select a meal. 
 * Includes sides, drink, and main entree
 * Writes users order to user specified file.

public class MealBuilder {
    
    /*
     * Main 
     * Sets up frame
     * @param args not used
     */
    public static void main(String[] args)
    {
        EventQueue.invokeLater(
           new Runnable()
           {
                public void run()
                {
                   MealBuilderFrame frame = new MealBuilderFrame();
                   frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                   frame.setVisible(true);
                }
           });
    }

}

    String file;
    File  writeTo; //= new File("hello.txt");
    BufferedWriter writer;
}
