03. VetClinic 85/100 - Java Advanced Retake Exam - 19 August 2020

Здравейте,

На задача VetClinic от Java Advanced Retake Exam - 19 August 2020 ми гърмят 2 теста. Предполагам, че проблема е или в toString() метода или в getStatistics() метода - обикновено там ми излиза грешка.

Условие:

Your task is to create a repository, which stores items by creating the classes described below.

First, write a Java class Pet with the following fields:

name: String
age: int
owner: String

The class constructor should receive name, age and owner. You need to create the appropriate getters and setters. The class should override the toString() method in the following format:

"{name} {age} ({owner})"

Next, write a Java class Clinic that has data (a collection, which stores the Pets). All entities inside the repository have the same fields. Also, the Clinic class should have those filelds:

capacity: int

The class constructor should receive capacity, also it should initialize the data with a new instance of the collection. Implement the following features:

Field data – List that holds added pets
Method add(Pet pet) – adds an entity to the data if there is an empty cell for the pet.
Method remove(String name) – removes the pet by given name, if such exists, and returns boolean.
Method getPet(String name, String owner) – returns the pet with the given name and owner or null if no such pet exists.
Method getOldestPet() – returns the oldest Pet.
Getter getCount – returns the number of pets.
getStatistics() – returns a String in the following format:
- "The clinic has the following patients:
  {name} {owner}
  {name} {owner}

(…)"

Constraints

The combinations of names and owners will always be unique.
The age of the pets will always be positive.

Examples

This is an example of how the Clinic class is intended to be used.

Sample code usage

// Initialize the repository

Clinic clinic = new Clinic(20);

// Initialize entity

Pet dog = new Pet("Ellias", 5, "Tim");

// Print Pet

System.out.println(dog); // Ellias 5 (Tim)

// Add Pet

clinic.add(dog);

// Remove Pet

System.out.println(clinic.remove("Ellias")); // true

System.out.println(clinic.remove("Pufa")); // false

Pet cat = new Pet("Bella", 2, "Mia");

Pet bunny = new Pet("Zak", 4, "Jon");

clinic.add(cat);

clinic.add(bunny);

// Get Oldest Pet

Pet oldestPet = clinic.getOldestPet();

System.out.println(oldestPet); // Zak 4 (Jon)

// Get Pet

Pet pet = clinic.getPet("Bella", "Mia");

System.out.println(pet); // Bella 2 (Mia)

// Count

System.out.println(clinic.getCount()); // 2

// Get Statistics

System.out.println(clinic.getStatistics());

//The clinic has the following patients:

//Bella Mia

//Zak Jon

public Pet getOldestPet() { int oldestAge = Integer.MIN_VALUE; int index = -1; for (int i = 0; i < this.data.size();i++) { if (this.data.get(i).getAge() >= oldestAge) { index = i; oldestAge = this.data.get(i).getAge(); } } return this.data.get(index); }
