Player Data saving methods?

Hi I am using this method to save data to a txt. source: bukkit

Code (Text):

public void logToFile(String message, String player)
    {
        try
        {
            File dataFolder = getDataFolder();
            if(!dataFolder.exists())
            {
                dataFolder.mkdir();
            }
            File saveTo = new File(getDataFolder(), player + ".txt");
            if (!saveTo.exists())
            {
                saveTo.createNewFile();
            }
            FileWriter fw = new FileWriter(saveTo, true);
            PrintWriter pw = new PrintWriter(fw);
            pw.println(message);
            pw.flush();
            pw.close();
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }
    }

which gives me for example:

Spoiler: player.txt

Freddy // location
x
y
z
hans //area
x
y
z
x
y
z
xxxxxxx //area
x
y
z
....

which is getting really big

I would prefer this (below), but I have no idea how to get the data out of the document

Spoiler: playerIWhant.txt

Freddy x y z
hans x y z x y z
xxxxxxx x y z x y z ......

or is the first method better than the second?
I allsow like this one, but it has a similar result like player.txt

could somebody link me or give a code example?
or has a better method to bind names to coordinates or areas?
it is all about the mbits ^^

Thanks in advance for any help

 

Thx for the reply
I was searching for a nice method how to save and compare areas and positions... and think, after trying some, .txt would be the best for me.
just the system should go through those files...

I was kind of stupid that I did not notice that i was in java and not in bukkit -_-
So I was looking for this

Code (Text):

String string = "x:y:z....";
String[] parts = string.split(":");
String part1 = parts[0];
String part2 = parts[1]; .....

worked all proper with my algorythm until I changed the code, and forgot where
I think it has something to do with my BufferedReaders/writers can I use them in that way?

could somebody see the error?

Code (Text):

public String fileManager (String player, String[] message, String info)
    {
        try
        {
            File dataFolder = getDataFolder();
            if(!dataFolder.exists())
            {
                dataFolder.mkdir();
            }
           
            File villages = new File(getDataFolder(), "villages.txt"); //villagesFile
            if (!villages.exists())
            {
                villages.createNewFile();
            }
           
            File personalFile = new File(getDataFolder(), player + ".txt"); //personal File
            if (!personalFile.exists())
            {
                personalFile.createNewFile();
            }
           
            BufferedReader villageReader = new BufferedReader (new FileReader (villages));
            BufferedWriter villageWriter = new BufferedWriter (new FileWriter (villages));
           
            BufferedReader fileReader = new BufferedReader (new FileReader (personalFile));
            BufferedWriter fileWriter = new BufferedWriter (new FileWriter (personalFile));
           
            if (info == "hasVillage?")
            {
                String hasVillage = fileReader.readLine();
                System.out.println("debug:" + hasVillage);
                if(hasVillage == null)
                {
                    fileWriter.close();
                    fileReader.close();
                    villageWriter.close();
                    villageReader.close();
                    return "noVillage";
                }
                else
                {
                    fileWriter.close();
                    fileReader.close();
                    villageWriter.close();
                    villageReader.close();
                    return "hasVillage";
                }
            }
}

the debug allways gives out null even if the text file has some code in it...

help is warmly accepted
