Science & Mathematics Writing to a text file in java

[power09]

Hello Iv made a game in java and I'm trying to save the current state of the game(score, lives remaining etc) and the high scores.

I know ill have to go about this by saving to a text file but the are a lot of ints and strings ill have to save, so is there a way to just input the the names of the variables instead of their actual value in the writing method?
But still have their value written on the text file?

And i guess each value would be written onto its own line so it is easy to parse the values back off the text file.

I was just wondering if someone could write an example method of something like this, because I'm struggling to find an example like this on stack overflow.

would be much appreciated
Cheers

Are you just wanting write to a file and not read it back in when the program restarts or both?

Yeah I want to save a bunch of int values and some strings, and get those values back when the program is run again

There are plenty of good java forums around. Java Ranch is one, have a look through there. There will be this example.

I have suggested in your other thread (same one as this) that you should try a StringTokenizer.

Hey guys thanks for trying to help, I worked it out last week, for the records what I was trying to do was this (to write too txt file):

int toSave = JOptionPane.showConfirmDialog(null, "Do You Want Save the HighScores", s, WIDTH);
                    if(toSave == JOptionPane.YES_OPTION){
                        try {                       
                            BufferedWriter highscores = null;
                            highscores = new BufferedWriter(new FileWriter("C:\\Documents\\NetBeansProjects\\Brickes\\HighScores.txt"));
                            System.out.println("get here?3");
                            highscores.append(firstplayer);
                            highscores.newLine();
                            highscores.append( String.valueOf(HighScore1));
                            highscores.newLine();
                            highscores.append(secondplayer);
                            highscores.newLine();
                            highscores.append(String.valueOf(HighScore2));
                            highscores.newLine();
                            highscores.append(thirdplayer);
                            highscores.newLine();
                            highscores.append(String.valueOf(HighScore3));
                            highscores.newLine();
                            highscores.append(forthplayer);
                            highscores.newLine();
                            highscores.append(String.valueOf(HighScore4));
                            highscores.newLine();
                            highscores.append(fithplayer);
                            highscores.newLine();
                            highscores.append(String.valueOf(HighScore5));
                            highscores.newLine();
                            highscores.close();
                            System.out.println("writhing highscores.....");           
                        } catch (IOException ex) {
                          System.out.println("I/O ERROR!");
                           
                        }
                    }
                    System.exit(0);

and this to read from:

  try{
      scan = new Scanner (new File("C:\\Documents\\NetBeansProjects\\Brickes\\HighScores.txt"));
      System.out.println("Loading HighScores");
      String P1 = scan.nextLine();
      String P1S = scan.nextLine();
      String P2 = scan.nextLine();
      String P2S = scan.nextLine();
      String P3 = scan.nextLine();
      String P3S = scan.nextLine();
      String P4 = scan.nextLine();
      String P4S = scan.nextLine();
      String P5 = scan.nextLine();
      String P5S = scan.nextLine();
      System.out.println(P1 +" : " +P1S);
      System.out.println(P2 +" : " +P2S);
      System.out.println(P3 +" : " +P3S);
      System.out.println(P4 +" : " +P4S);
      System.out.println(P5 +" : " +P5S);
     
      firstplayer= P1;secondplayer = P2; thirdplayer = P3; forthplayer =P4; fithplayer= P5;
      HighScore1 = Integer.parseInt(P1S); HighScore2 = Integer.parseInt(P2S);HighScore3 = Integer.parseInt(P3S);HighScore4 = Integer.parseInt(P4S);HighScore5 = Integer.parseInt(P5S);
     
  }    catch(Exception e){
            System.out.println("could not find file");
  }

Nice work power09

I see you use NetBeans, I used to use NetBeans too until it completely ****ed up one of my projects.
