if you cant do it please dont waste my question

JAVA

Run this program, understand it, design a GUI for this program. Your GUI should allow user interaction with the applications. The GUI must allow for user input and output file creation. Said GUI must be able to perform the tasks of file creation, data input and saving, and data retrieval and output. You should also include instructions to the user on what and how to use your program. Remember user-friendly. You should not have to rewrite any of the example programs just modify them to use a GUI.

Add comments to code please

import java.io.PrintWriter; import java.io.FileNotFoundException; import java.util.Scanner; public class TextFileOutputDemo { public static void main(String[] args) { String fileName = "out.txt"; //The name could be read from //the keyboard. PrintWriter outputStream = null; try { outputStream = new PrintWriter(fileName); } catch(FileNotFoundException e) { System.out.println("Error opening the file " + fileName); System.exit(0); } System.out.println("Enter three lines of text:"); Scanner keyboard = new Scanner(System.in); for (int count = 1; count <= 3; count++) { String line = keyboard.nextLine( ); outputStream.println(count + " " + line); } outputStream.close( ); System.out.println("Those lines were written to " + fileName); } }
