Answer 1

class Animal {
    private String name;
    private int age;

    public Animal(String name, int age) {
        this.name = name;
        this.age = age;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
}

class Cheetah extends Animal {

    private static int speed;

    public Cheetah(String name, int age) {
        super(name, age);
    }

    public static int getSpeed() {
        return speed;
    }

    public static void setSpeed(int speed) {
        Cheetah.speed = speed;
    }
}

class CheetahTest {

    public static void main(String[] args) {
        Cheetah cheetah = new Cheetah("Tom", 5);
        Cheetah.setSpeed(56);
        System.out.println("Name: " + cheetah.getName());
        System.out.println("Age: " + cheetah.getAge());
        System.out.println("Speed: " + Cheetah.getSpeed());
    }
}
