Java Desktop App - Zoo Management System

Project description

You have been tasked to create a Zoo management system.

The Zoo has a number of Animals. These Animals are broken down into types:
- Mammal
- Reptile
- Avian
- Aquatic
- Insect

Example Animals:

Mammal:

Tiger:

date of birth, date of arrival, gender, ofspring, medicaton, vaccine, exhibit number

Mammal:

Avian

Bat

date of birth, date of arrival, fight, gender, ofspring, medication, vaccine, exhibit number

Each Animal has a Zoo keeper that looks afer it:
- Zoo keepers are only allowed to care for animals if they are qualified to do so.
- A zoo keeper can look afer a max of 3 Animal types for a max of 10 animals.

The system must allow a user to:
- Search for Animals.
- Search for Keepers.
- Add new animals.
- Add new keepers.
- Update animals.
- Update keepers.

Your system must be run on test data before the Zoo will accept it:

You are required to have a data set of at least 100 animals and 40 zoo keepers.

Ejemplo Código

public class Test {
    
    public static void main(String[] args) {
        Cat c = new Cat();
        System.out.println(c.health);
        
        Dog d = new Dog();
        System.out.println(d.health);
        
        
        // // Upcasting
        Mammal m = c;           // Although there's no need to for programmer to upcast manually, it's legal to do so:
                                // Mammal m = (Mammal) new cat();
                                
        System.out.println(c);  // This print:               upcastingdowncasting.Cat@15db9742                               
        System.out.println(m);  // This will print the same: upcastingdowncasting.Cat@15db9742
                                // As you can see, Casting does not change the actual object type
                                // Cat is still exactly the same Cat after upcasting.
                                // It didn't change to a Mammal, it's just being labelled Mammal right now.
                                // This is allowed, because Cat is a Mammal.
        
                                        
        // // Downcasting
        if(m instanceof Cat){   // testing if the Animal is a Cat
            System.out.println("It's a Cat! Now I can downcast it to a Cat, without a fear of failure.");
            Cat c1 = (Cat)m;    // Manual downcasting back to a Cat
        }
        
        // The following code will compile, but throws "java.lang.ClassCastException: Mammal cannot be cast to Cat" exception during runTime,
        // because I’m trying to cast a Mammal, which is not a Cat, to a Cat.
        Mammal m1 = new Mammal();
        Cat    c2 = (Cat)m1;                        
                                
    }
