title: Java read file and remove line, Cant figure out error
body: <p>I am working on a project that has a method that reads a file, finds a a string that is passed in writes a new file called temp (that doesnt have the passed in line in it) and then deletes the original and renames temp to the opriginal name. I can run it without errors but it outputs nothing into the new file. I have done the usually debugging and found that the error lies in the lines where it writes out the line to the new file. I feel like I have made a small error calling something wrong. Any help solving it would be great...</p>
  
  <p>Here is the code</p>
  
  <pre><code>public static void LineDelete(String Filename, String Content) throws IOException {
      try {
          File flights = new File("AppData/" + Filename);
          File temp;
          temp = new File("AppData/temp.txt");
          FileWriter fstream;
          BufferedWriter out;
          try (Scanner sc = new Scanner(flights)) {
  
              fstream = new FileWriter("AppData/temp.txt", true);
              out = new BufferedWriter(fstream);
              boolean exis = temp.exists();
              if (exis) {
                  temp.delete();
                  temp = new File("AppData/temp.txt");
                  boolean createNewFile = temp.createNewFile();
              } else {
                  boolean creatNewFile = temp.createNewFile();
              }
              String f;
              while (sc.hasNextLine()) {
                  f = sc.nextLine();
                  if (!f.equals(Content)) {
  
                      out.newLine();
                      out.write(f);
  
                  }
  
              }
          }
          fstream.close();
          //out.close();
          flights.delete();
          File flightsn = new File("AppData/" + Filename);
          temp.renameTo(flightsn);
      } catch (FileNotFoundException ex) {
          Logger.getLogger(FileWrite.class.getName()).log(Level.SEVERE, null, ex);
      }
  }
