如何在JAVA中实现这个类图？

// 定义一个父类Animal
class Animal {
    private String name;
    
    public Animal(String name) {
        this.name = name;
    }
    
    public void eat() {
        System.out.println(name + " is eating.");
    }
}

// 定义一个子类Dog继承自Animal
class Dog extends Animal {
    public Dog(String name) {
        super(name);
    }
    
    public void bark() {
        System.out.println("Dog is barking.");
    }
}

// 定义一个子类Cat继承自Animal
class Cat extends Animal {
    public Cat(String name) {
        super(name);
    }
    
    public void meow() {
        System.out.println("Cat is meowing.");
    }
}

public class Main {
    public static void main(String[] args) {
        Dog dog = new Dog("Tom");
        dog.eat(); // 输出：Tom is eating.
        dog.bark(); // 输出：Dog is barking.
        
        Cat cat = new Cat("Jerry");
        cat.eat(); // 输出：Jerry is eating.
        cat.meow(); // 输出：Cat is meowing.
    }
}
