Hello Friends,

its me again with another question.

I am trying to program a PhoneBook at the moment and I got stuck at a specific part.
When I want to search my PhoneBook I need to compare the LastNames and FirstNames but I am not sure how I can access the information.

The entries are safed in an array in the following form:



Know I when I want to write an algorithm which looks for the last name (second entry) first and the first name second I am not sure how I can access the information...

How can i get for example entries[0]firstName only or lastName only?

Thank you very much for the help.

I presume you have getFirstName(), and getLastName(), and getPhoneNumber() methods. You can iterate the array:

Alternative, using the Java8+ constructs:-Afraid I haven't got the time to explain everything in detail. I have decided to use a PhoneNumber class rather than using Strings for the phone number.
