public class Main {
  public static void main(String[] argv) throws Exception {
    // Create a file handler that uses 3 logfiles, each with a limit of 1Mbyte
    String pattern = "my%g.log";
    int limit = 1000000; // 1 Mb
    int numLogFiles = 3;
    FileHandler fh = new FileHandler(pattern, limit, numLogFiles);
