Question

I’m trying to compare my highscore that I saved in A file to compare with an integer. So I always will get three characters out of my file, butt if I control it it doesn’t put my new score in it.

try{
                String FILENAME = "HanoiScore1File";
                FileInputStream fos = openFileInput(FILENAME);
                byte[] b = new byte[2];
                fos.read(b);
                fos.close();
                Data = new String(b);
                Score2 = Integer.parseInt(Data);
            }catch (java.io.FileNotFoundException e) {
              } catch (IOException e) {
                e.printStackTrace();
            }
            if(Score2>Score){
                try{
                    String FILENAME="HanoiScore1File";
                    Data=Integer.toString(Score);
                    FileOutputStream fostemp = openFileOutput(FILENAME, Context.MODE_PRIVATE);
                    fostemp.write(Data.getBytes());
                    fostemp.close();
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }

Answer 1

String FILENAME = "HanoiScore1File";

//Read the score
Scanner scanner = new Scanner(new File(FILENAME));
int Score = scanner.nextInt();
scanner.close();

//Write the score
PrintWriter printWriter = new PrintWriter(new File(FILENAME));
printWriter.println(Score);
printWriter.close();

This Works but the mistake I made was

if (Score2>Score)

Score2 was always 0, which will never be bigger than Score, so It didn’t save the high score.
