I am currently doing a programming assignment and it says that we should
“store all the data in a data file and need to check the compatibility of the user PIN and account no. validity”

Unfortunately my lecturer has not taught us about data files, and when I googled I found two different answers,

  1. Store data in notepad (.txt) file
  2. Store data in csv file

MY QUESTION IS WHICH ONE IS A DATA FILE? and how do you retrieve the user PIN (after its typed from buffer reader) to check whether both are correct?
Any Help is GREATLY APPRECIATED!!

    from wikipedia:

    A data file is a computer file which
    stores data for use by a computer
    application or system.

    So both a *.txt file and a *.csv file are data files.

    A *.csv (comma-seperated values) file is in essence a *.txt file that separates your values by a ,

    The 2 methods you found should do about the same, but it will be easier to use the csv-method.
