    • load

      public static Statistics load() throws IOException

      This static method loads the statistics from the CSV_FILE file located at the path defined by the CSV_FILE constant in the Statistics class. The method uses a CSVReader object to read the data from the file.

      If the CSV_FILE file does not have the expected headers, an IOException is thrown. The method returns a Statistics object with the values read from the CSV_FILE file.

      If an IOException occurs during the file reading process, it is caught and printed to the standard error stream. If a CsvValidationException is thrown during the file reading process, it is handled internally and an empty Statistics object is returned.

      Returns:
      a Statistics object with the values read from the CSV_FILE file, or an empty Statistics object if there was a problem with the CSV file format
      Throws:
      IOException - if there is a problem with the file reading process or the CSV file headers are invalid
