hello and thank you for taking the time to look at my problem.
I have some of hte code done out but i need help.
I need to know what goes inside where the dots are.
Thast is where the problems are. Thanks again and any help will be appreciated

class AddressBook {

String []fieldNames;

String [][] book;

public void initAddressBook (String [] fields, String[][] records) {

fieldNames = fields;

book = records;

}// end of initAddress

private int translate(String field) { //covert field name to index into array book

int result;

for (result = 0; !fieldNames[result].equals(field); result++)

;

return result;

} // end of translate

private String [][] storeIt (String results[][], String record[]) {

int records =0;

String temp[][] =null;

if (results == null){

results = new String[1][];

results[0] = record;

} //end of storeIt

else {

records = results.length;

temp = new String[records+1][];

temp[records] = record;

for (int i =0 ; i <records; i++)

temp = results;

results = temp;

}

return results;

}

public AddressBook find( String aField, String key) {

int field = translate(aField);

int records = book.length;

String results[][]=null;

AddressBook resultingSet = new AddressBook();

................................

..........................

. ...............................

// careful here!

// We are creating an AddressBook with the same fieldsandcontaining the records that matched

// write here the code to create it and initialize it before returning it

return resultingSet;

} // end of find

public void sort( String aField)

{

int a, b;

int field = translate(aField);

...................................................

...... ......................................

if(book[field].compareTo(book[b + 1][field]) > 0)//Compares the strings

......................................................

}

public void printRecords() {

int records = book.length;

int fields = book[0].length;

for (int i = 0 ; i < records; i++) {

for (int j =0 ; j < fields; j++)

System.out.print(book[j] + " ");

System.out.println("");

}

}

} //end of class

public class AddressBookTest {

public static void main (String [] args) {

String [] fields = {"Name", "Phone", "Address","City","State","Zip"};

String data [] [] = { {"John", "2126223456", "123 X Road", "Histown", "PA", "12345"},

{"Mary", "5084567898", "5 Yo Street", "Hertown", "MA", "23456"},

{ "Bill", "2124356788", "13 Badluck St", "Histown", "PA", "12345"},

};

AddressBook addrBook = new AddressBook();

addrBook.initAddressBook(fields,data);

AddressBook s = addrBook.find("Name", "ry"); //return all records containing 123 in the ZIP

s.printRecords();

addrBook.sort( "Name") ; // sort all records by zip code

addrBook.printRecords();

} // end of main

} // end of class
