Spigot Plugin, nobody on Server

Question

I try to make a spigot plugin that can detect if nobody is on the server. I need this for a timer, if nobody is on the server, it should stop the timer and save the time of the timer in a text file. Is there any way I can do this with a plugin. Thanks for every help, Aaron.

How to create text files:

        try {
            File file = new File(Yourplugin.getPlugin(YourPlugin.class).getDataFolder().getPath(), "filename.txt");
            file.getParentFile().mkdirs();
            file.createNewFile();
        } catch (IOException exception){
            System.out.println(exception.toString());
        }

How to read from text files:

        File file = new File(YourPlugin.getPlugin(Yourplugin.class).getDataFolder().getPath(), "filename.txt");
        BufferedReader br = new BufferedReader(new FileReader(file));
        String line = br.readline(); //can be null, if nothing is in file

How to write to Files:

            File file = new File(YourPlugin.getPlugin(Yourplugin.class).getDataFolder().getPath(), "filename.txt");
            BufferedWriter wr = new BufferedWriter(new FileWriter(file));
            br.write("yourtime");

You should make a try catch construction in every example like in the first one.
