Phonebook program??

im not looking for someone to do the program for me, but i would like a starting point and maybe some tips. im doing the program in java. the program will allow the user to insert a persons phone number and name, or search for either the name or phone number of a certain person. any hints will be appreciated. thank you.

Ok, if u do not want to talk about databases, then keep reading.
Write a class named "PhoneBook", this class should contain at least the following instance variables:
1- Name (person's name).
2- Home_phone_number.
3- Office_phone_number.
4- Cellular_phone_number.
5- E-mail_address.
6- Street_adress.

U may have this question in ur head: "What if he has more than one of those variables, for example what if he has more than one e-mail address??", in that case, if u want to enable users to enter more than one thing in each entry, then these variables should be arrays, not normal variables, for example an array that stores all the e-mail addresses.

The class should contain the following functions:
1- Print (prints each person's details: phones, e-mails, addresses, ... etc)

2- Search for people (records) by name, e-mail, phone numbers, ... etc.

3- Delete a record, which requires searching first for the record to be deleted.

In application, u should store all records that have been created in a list or an array of type PhoneBook, the reason for this is that u r going to search for records, arrays and lists are easy to search, for example:
PhoneBook book1[ ] = new PhoneBook[10];
for(int c=0;c<10;c++)
{
book1[c]=new PhoneBook( // put the parameters of the constructor here);
}
Then write a search method for searching for names, addressesm ,,,,etc., then apply it:
search([]book1, "Zakari");

Thats a part of what i thought about, there are too much details to mention here.

Good luck
Bye
