Thread: How to save statistics of a game in a binary file instead of txt file?

Yes I would of said the same thing too. It will be the same as working with a .txt file.

Hey FretDancer69,

I have written this example for you. It will write the scores to a file and then read the file and print the scores.

import java.io.*;
import java.util.Scanner;
import java.io.FileNotFoundException;
 
public class FretDancer69 {
 
    /**
     * JavaProgrammingForums.com
     */
    public static File file = new File("file.bin");
    public static int win, lose, tie;
    public static int winFile, loseFile, tieFile;
 
    public static void writeFile() {
 
        String newLine = System.getProperty("line.separator");
 
        try {
            Writer output = null;
            output = new BufferedWriter(new FileWriter(file));
 
            output.write(Integer.toString(win));
            output.write(newLine);
            output.write(Integer.toString(lose));
            output.write(newLine);
            output.write(Integer.toString(tie));
            output.close();
            System.out.println("File written");
 
            readFile();
 
        } catch (Exception e) {
            System.out.println("Error writing file");
            e.printStackTrace();
        }
    }
 
    public static void readFile() {
 
        System.out.println("Reading file");
 
        try {
            Scanner sc = new Scanner(file);
 
            while (sc.hasNextLine()) {
 
                winFile = sc.nextInt();
                loseFile = sc.nextInt();
                tieFile = sc.nextInt();
            }
            sc.close();
            System.out.println("Read file");
        } catch (FileNotFoundException e) {
            System.out.println(file + " cannot be found!");
        }
    }
 
    public static void main(String[] args) throws Exception {
 
        win = 10;
        lose = 2;
        tie = 1;
 
        FretDancer69 fd = new FretDancer69();
        fd.writeFile();
 
        System.out.println();
        System.out.println("Results from file: ");
        System.out.println("Wins = " + winFile);
        System.out.println("Loses = " + loseFile);
        System.out.println("Ties = " + tieFile);
    }
}

Example output:

File written
Reading file
Read file

Results from file:
Wins = 10
Loses = 2
Ties = 1
