Question

Write a java project that reads a sequence of up to 25 pairs of names and postal (ZIP) codes, street address, city, state, and 10-digit phone number for individuals. Store the data in an object designed to store a first name (string), last name (string), and postal code (integer), street address (string), city( string), state (string), and 10-digit phone number (long integer, contains area code and does not include special characters such as '(', ')', or '-' . Assume each line of input will contain strings followed by an integer value, each separated by a tab character. Then, after the input has been read in, print the list in an appropriate format to the screen. Need to Store the data in an ArrayList object. DATA SHOULD BE READ FROM INPUT FILE

Answer 1

Record.java

public class Record {
private String firstName, lastName;
private int postalCode;
private String streetAddress, city, state;
private long phoneNumber;
  
public Record()
{
this.firstName = "";
this.lastName = "";
this.postalCode = 0;
this.streetAddress = "";
this.city = "";
this.state = "";
this.phoneNumber = 0;
}

public Record(String firstName, String lastName, int postalCode, String streetAddress,
String city, String state, long phoneNumber)
{
this.firstName = firstName;
this.lastName = lastName;
this.postalCode = postalCode;
this.streetAddress = streetAddress;
this.city = city;
this.state = state;
this.phoneNumber = phoneNumber;
}

public String getFirstName() {
return firstName;
}

public String getLastName() {
return lastName;
}

public int getPostalCode() {
return postalCode;
}

public String getStreetAddress() {
return streetAddress;
}

public String getCity() {
return city;
}

public String getState() {
return state;
}

public long getPhoneNumber() {
return phoneNumber;
}

public void setFirstName(String firstName) {
this.firstName = firstName;
}

public void setLastName(String lastName) {
this.lastName = lastName;
}

public void setPostalCode(int postalCode) {
this.postalCode = postalCode;
}

public void setStreetAddress(String streetAddress) {
this.streetAddress = streetAddress;
}

public void setCity(String city) {
this.city = city;
}

public void setState(String state) {
this.state = state;
}

public void setPhoneNumber(long phoneNumber) {
this.phoneNumber = phoneNumber;
}
}

RecordReader.java (Main class)

import java.io.File;
import java.io.FileNotFoundException;
import java.util.ArrayList;
import java.util.Scanner;

public class RecordReader {
  
private static final String FILENAME = "records.txt";
  
public static void main(String[] args)
{
Scanner fileReader;
ArrayList<Record> records = new ArrayList<>();
  
try
{
fileReader = new Scanner(new File(FILENAME));
while(fileReader.hasNextLine())
{
String line = fileReader.nextLine().trim();
String[] data = line.split(" ");
String fName = data[0];
String lName = data[1];
int zip = Integer.parseInt(data[2]);
String street = data[3];
String city = data[4];
String state = data[5];
long phone = Long.parseLong(data[6]);
  
records.add(new Record(fName, lName, zip, street, city, state, phone));
}
fileReader.close();
}catch(FileNotFoundException fnfe){
System.out.println("File not found: " + FILENAME);
System.exit(0);
}catch(NumberFormatException nfe){
System.out.println("Unknown character encountered!\nExiting..");
System.exit(0);
}
  
System.out.printf("%15s %20s %30s %15s %15s %15s\n------------------------------------------------"
+ "-------------------------------------------------------------------\n",
"Name", "Postal Code", "Street Address", "City", "State", "Phone Number");
  
for(Record rec : records)
{
System.out.printf("%15s %20d %30s %15s %15s %15d\n",
rec.getFirstName() + " " + rec.getLastName(), rec.getPostalCode(), rec.getStreetAddress(),
rec.getCity(), rec.getState(), rec.getPhoneNumber());
}
}
}

Note: The input file "records.txt" has to be created before starting the program. The file needs to be created within the project directory where the .java files will reside.

INPUT FILE (records.txt) : Data inside the file may vary, but each field needs to be separated by tabs
