How to go down lines when trying to write to a file with Java

Question

Using the code below, I am trying to make a log for a plugin, though, every time it makes a entry I want it to go below the other entry. Though, when I test it, it writes the second entry but the first entry gets deleted.

if (commandLabel.equalsIgnoreCase("logmeup")) {
    entry++;
    entry3 = entry * 3;
    FileWriter fw= null;
    File file =null;

    try {
        file = new File("playerLog.txt");
        if(!file.exists()) {
            file.createNewFile();
        }
        fw = new FileWriter(file);
        if (entry == 1) {
            fw.write("Name: " + player.getDisplayName() + "\nIP: " + player.getAddress() + "\nLocation: " + player.getLocation() + "\n");
            fw.close();
        }
        else {
            while (entryloop < entry3) {
                entryloop++;
                fw.write(System.getProperty( "line.separator" ));
            }
            entryloop = 0;
            fw.write("Name: " + player.getDisplayName() + "\nIP: " + player.getAddress() + "\nLocation: " + player.getLocation() + "\n");
            fw.close();
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
}

Pastebin source contains only 26 lines, fix the line number in the question. — Dawid Bugajewski, May 17 '15 at 01:48

Flaged as dupe yet I will answer it once again: Pass second argument of FileWriter as true to make it go into append mode.

fw = new FileWriter(file,true);

Where should I put that in my code? – sneakyevil May 17 '15 at 01:53
Just add the true parameter on line 11 of example – Dawid Bugajewski May 17 '15 at 01:55
