ID Name Address City State Zip
1. John Small 123 Main St. Laurel MD 20708
2. Fig F. Big 1145 Techie Dr. New York NY 45446

i'll be more precise!!
Implement an Object called AddressReader that will be able to open and read the file entitled AddressBook.dat.
1.John Smith 123 Main St. Laurel MD 20708
2.Greg F. Jones 1145 Technology Rd. New York NY 45456
3.Tim Roberts 1324 Basswood Dr. Arlington VA 20166
File Format Rules

Position number followed by a .
Full name either first name and last name or first name, middle initial with a . and last name
Address- Street number, Street name, and either Dr, St, or Rd which always ends with a .
City - 1 or more words
State - 2 letter abbreviation
Zip - 5 number code
Class AddressReader will need to have the following functions
int getTotalEntries( );
String getName(int position) - returns the name as a String according to the position provided in the parameter.
String getAddress(int position)
String getCity(int position)
String getState(int position)
String getZip(int position)
There will be a Class Client that has its own main and will instantiate an AddressReader and call its methods.
class Client {
public static void main(String[] args) {
AddressReader add = new AddressReader();
for (int i=0;i<add.getTotalEntries(); i++){
String name = add.getName(i);
String address = add.getAddress(i);
String city = add.getCity(i);
String state = add.getState(i);
String zip = add.getZip(i);

int entry = i+1;
//prints out the contents of AddressBook.dat
System.out.println("Address Entry: "+ entry);
System.out.println("Name: "+ name);
System.out.println("Address: "+address);
System.out.println("City: "+city);
System.out.println("State: "+state);
System.out.println("Zip: "+zip);

This looks a lot like a homework assignment
Just a warning that we offer help but not solutions for homework
The Java Ranch has thousands of visitors every week, many with surprisingly similar names. To avoid confusion we have a naming convention, described at
We require names to have at least two words, separated by a space, and strongly recommend that you use your full real name. Please edit your profile and select a new name which meets the requirements.
I agree. Here's the link:
