    copied!<p>Let me preface this by saying that I'm extremely new to java. This is my eighth week in the class and I'm stuck on a project. Here is what I have so far:</p> <pre><code>import java.io.*; public class Guitar { // Initialize variables boolean isPlaying; boolean inTune; char[] guitStrings = {'D', 'G', 'C', 'A'}; // Guitar strings int numOfStrings = 4; // Number of strings the guitar has. public void Guitar(){ isPlaying = false; // Guitar is not playing by default. inTune = false; // Guitar is not tuned by default. System.out.println("The guitar is not tuned and is not playing."); } public void isPlaying(){ System.out.println("Your guitar is now playing!"); isPlaying = true; // Set guitar to playing } public void inTune(){ System.out.println("Your guitar is now tuned!"); inTune = true; // Set guitar to tuned. } public void stopPlaying(){ isPlaying = false; // Set isPlaying to false. System.out.println("Your guitar has finished playing!"); } public void notes(){ System.out.println("The guitar has played a total of " + numOfStrings + " strings and they are: " + guitStrings[0] + "," + guitStrings[1] + "," + guitStrings[2] + "," + guitStrings[3]); } public static void main(String[] args) throws IOException{ java.io.File file = new java.io.File("guitartest.txt"); if(file.exists()){ System.out.println("File already exists!"); System.exit(1); } // Create a file java.io.PrintWriter output = new java.io.PrintWriter(file); Guitar[] guit = new Guitar[10]; for (int i = 0; i &lt; guit.length; i++){ guit[i] = new Guitar(); guit[i].Guitar(); guit[i].inTune(); guit[i].isPlaying(); guit[i].notes(); guit[i].stopPlaying(); } } } </code></pre> <p>This program does everything I need it to do, but we have one last step on the project. I must output this to a text file from the command line. I've changed the last bit of code to this: </p> <pre><code>public static void main(String[] args) throws IOException{ java.io.File file = new java.io.File("guitartest.txt"); if (file.exists()){ System.out.println("This file already exists!"); System.exit(1); } // Create a file java.io.PrintWriter output = new java.io.PrintWriter(file); Guitar[] guit = new Guitar[10]; // Create 10 instruments for (int i = 0; i &lt; guit.length; i++){ output.println(guit[i] = new Guitar()); output.println(guit[i].Guitar()); output.println(guit[i].inTune()); output.println(guit[i].isPlaying()); output.println(guit[i].notes()); output.println(guit[i].stopPlaying()); } } </code></pre> <p>This compiles the codes, and displays the results I want in the console, but the text file guitartest.txt is completely blank. I am NOT looking for someone to complete this assignment for me, I'm just looking for any advice or resources you could point me to. Thank you very much!</p>
