Specifications

  • Create a class named CountryIO that contains these methods:

public static void readData()

public static void writeData(String text)

  • Store the list of countries in a text file named countries.txt. If the countries.txt file doesn’t exist, the ReadAFile class should create it. This class should use buffered I/O streams, and it should close all I/O streams when they’re no longer needed.

Possible enhancements (10pts extra credit)

  • Modify the app so it includes a menu choice that allows the user to delete a country from the file
