Question

I need a java oriented program that is for a pet store. The program must have a pet store class and a driver class where the main method is located and tests the program. The program must read data from a text file. The code must be able to read:

A last name

A first name

An address

A client ID

number of visits

Outstanding Balance

an array of Pets (aggregation)

Each Pet will have:

A name

An animal type

A weight

A date of last rabies shot (String)

A date of last visit (String)

Also, Write the constructor methods and toString ( ) method for each class. Write an equals( ) method for the client based on the client id Write a program that reads in data from a file to create an array of five clients. The driver will print each client's information (along with the pet name and type)

File Structure:

Last name, first name, address, ID, number of visits, balance, number of pets, pet name, animal type, weight, rabies date, last visit date.

Explanation / Answer

Pet.java

package petstore;

public class Pet {
String petName;
String petType;
double weight;
String lastRabiesShot;
String lastVisit;

/**
*
* @param name
* @param type
* @param weight
* @param lastRabiesShot
* @param lastVisit
*/
public Pet(String name, String type, double weight, String lastRabiesShot, String lastVisit) {
this.petName = name;
this.petType = type;
this.weight = weight;
this.lastRabiesShot = lastRabiesShot;
this.lastVisit = lastVisit;
}

public String getName() {
return petName;
}

public String getType() {
return petType;
}

public double getWeight() {
return weight;
}

public String getLastRabiesShot() {
return lastRabiesShot;
}

public String getLastVisit() {
return lastVisit;
}

@Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;

Pet pet = (Pet) o;

if (Double.compare(pet.getWeight(), getWeight()) != 0) return false;
if (!getName().equals(pet.getName())) return false;
if (!getType().equals(pet.getType())) return false;
if (!getLastRabiesShot().equals(pet.getLastRabiesShot())) return false;
return getLastVisit().equals(pet.getLastVisit());
}

@Override
public int hashCode() {
int result;
long temp;
result = getName().hashCode();
result = 31 * result + getType().hashCode();
temp = Double.doubleToLongBits(getWeight());
result = 31 * result + (int) (temp ^ (temp >>> 32));
result = 31 * result + getLastRabiesShot().hashCode();
result = 31 * result + getLastVisit().hashCode();
return result;
}

   @Override
   public String toString() {
       return "Pet [petName=" + petName + ", petType=" + petType + ", weight=" + weight + ", lastRabiesShot="
               + lastRabiesShot + ", lastVisit=" + lastVisit + "]";
   }

}

Client.java

package petstore;

public Pet[] getPests() {

@Override
public boolean equals(Object o) {
if (this == o) return true;

Client client = (Client) o;

if (getClientId() != client.getClientId()) return false;
if (getNumberOfVisit() != client.getNumberOfVisit()) return false;
if (Double.compare(client.getOutstandingBalance(), getOutstandingBalance()) != 0) return false;
if (!getLastName().equals(client.getLastName())) return false;
if (!getFirstName().equals(client.getFirstName())) return false;
if (!getAddress().equals(client.getAddress())) return false;
// Probably incorrect - comparing Object[] arrays with Arrays.equals
return Arrays.equals(getPests(), client.getPests());
}

@Override
public int hashCode() {
int result;
long temp;
result = getLastName().hashCode();
result = 31 * result + getFirstName().hashCode();

   @Override
   public String toString() {
       return "Client [lastName=" + lastName + ", firstName=" + firstName + ", address=" + address + ", clientId="

               + ", pests=" + Arrays.toString(pests) + "]";
   }

TestClass.java

package petstore;

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

public class TestClass {

}

} catch (FileNotFoundException e) {
e.printStackTrace();
}

}

/**
* This Method will Print the Clients List
*/
public static void printClients(){
for(Client client:clients){
System.out.println(client);
}
}
public static void main(String[] args) {

readFile("pet_data.txt");
