You are going to create a PhoneRecord class containing the following properties:
firstName - which is a String lastName - which is a String
number - which should also be a String
The properties will be public, and it should have two constructors: one that simply constructs the string and another that accepts values for first name, lastname and phone number.
You should also create a class called Phone Book
. It should contain an array of Phone Records and a count of how
many records there actually are. The number of records is passed to it by the
constructor call, i.e.,:
PhoneBook pb = new PhoneBook(3);
will construct a phone book that can contain up to 3 listings.
The methods are:
readRecord() - which reads in a new
phone record. toString(int i) - which returns a
string containing record #i writeRecord(int i) - which writes record #i . writeBook() - which writes the entire phone book.Write another class that uses the phone book, obtaining its size as a command line argument. Read in several records, write one or two of them and write the whole phone book.
