Question

Write a class called Animal that contains a static variable called count to keep track of the number of animals created. Your class needs a getter and setter to manage this resource. Create another variable called myCount that is assigned to each animal for each animal to keep track of its own given number. Write a getter and setter to manage the static variable count so that it can be accessed as a class resource

Answer 1

class Animal {
    private static int count = 0;
    private int myCount;

    public Animal() {
        myCount = ++count;
    }

    public static int getCount() {
        return count;
    }

    public static void setCount(int count) {
        Animal.count = count;
    }

    public int getMyCount() {
        return myCount;
    }
}

class AnimalTest {

    public static void main(String[] args) {
        System.out.println("Number of animals created: " + Animal.getCount());
        Animal animal1 = new Animal();
        System.out.println("Number of animals created: " + Animal.getCount());
        Animal animal2 = new Animal();
        System.out.println("Number of animals created: " + Animal.getCount());
        Animal animal3 = new Animal();
        System.out.println("Number of animals created: " + Animal.getCount());
        System.out.println("Count of animal1: " + animal1.getMyCount());
        System.out.println("Count of animal2: " + animal2.getMyCount());
        System.out.println("Count of animal3: " + animal3.getMyCount());
    }
}
