Hello guys, it's me again with the Flappy Bird game. I'd like to make a 'best score' method that is saved in a txt file that i've created. And i need it to always show the best score on the death screen. Here's what i managed to do (steal) so far:

BufferedWriter file = null;
        try 
        {
            file = new BufferedWriter(new FileWriter("score.txt"));            
            file.write(""+score);
            file.close();
        }
        catch (IOException ioe) 
        {
            ioe.printStackTrace();
        }
        finally
        {
            try {
                file.close();
            }
            catch (IOException ioe) {
                ioe.printStackTrace();
            }
        }

It just saves the last score to the txt file.

That is what the code you have acquired does -- it saves the current score to the file. If you want it to only save the current score when it is the best score, then you need to compare the two to determine if the current score is indeed the best one. This means you need to read from the file first; then, compare; then write the current score if better. After that, you can display the true best score. Time to steal some more code. Save the above code for when the current score IS better.

If you don't want to steal more code which you (probably) can't understand, try to use the UserInfo class which can create an .csv file and read from it without complicated code.

Thank's guys. Danpost, i understand what you are saying but my biggest problem is reading the file.

It is almost the same except with readers instead of writers:

String line = null;
BufferedReader br = null;
try
{
    br = new BufferedReader(new FileReader("score.txt"));
    line = br.readLine();
    br.close();
}
catch(Exception e)
{
    System.out.println(e);
    try { br.close(); } catch (Exception x){}
    line = "0";
}
if (score > Integer.parseInt(line))
{
    // etc.
