This caused opencsv not to read from those readers. Returns: True if CSVReader will verify the reader before reads. False otherwise
  3. Reading CSVs with OpenCSV is faster than with Apache Commons CSV because the CSVWriter is implemented to be multi-threaded, when using the CSVToBean.parse () method. The CSVReader is also implemented using Java Iterable, so it is possible to manage both memory and time constraints based on the implementation method you choose
