Hello,

I'm preparing for my final exam and this question was part of the book and I simply am a little confused as to how I should approach it. It seems to me that there is missing info, but I believe it's designed that way. Is it possible to answer this question? I genuinely just dont understand, completing it and adding comments to the code would be greatly appreciated! I wouldn't usually ask to complete it but I am sincerely confused. I tried back tracking but my end result was not running as intended unfortunately. I wrote out the skeletons below.

public class PhoneBook {

//firstAvailableIndex keeps track of indexes used,

//as there might be less data than max array size.

int firstAvailableIndex;

String owner;

String[] contacts;

//Q.25 constructor no-arg

public static void main (String[] args) {

}

public PhoneBook(String owner, int size) {

//Q.24, complete

}

//Q.26, copy constructor

//Q.27, setter and getter

public boolean addContact(String name, long cell) {

//Q.28, complete

return false;

}

public String getPhoneBookDetails() {

return owner;

}

}

public class PhoneBookTest {

private static final int COUNT=2;

private static final String[] NAMES =

{"Jack", "Jill", "Joe", "Jacob", "Janet"};

private static final int [] NUMBERS =

{111, 222, 333, 444, 555};

public static void main (String[] args) {

PhoneBook book = new PhoneBook("John", COUNT);

//Q.30 complete body of loop

for ( int i=0; 1<=COUNT; i++) {

book.addContact(NAMES[i], NUMBERS[i]);

}

//Q.31 print book

}

}
