实现一个双向适配器实例，使得猫(Cat)可以学狗(Dog)叫，狗可以学猫抓老鼠。绘制相应类图并使用代码编程模拟。 1、画出UML类图（30分） 2、使用Java语言编程实现（30分）

1. UML类图

+-----------------------+

2. Java代码

Animal.java

public interface Animal {
    void setCallSound(String sound);
    void call();
    void setAction(String action);
    void action();
}

Cat.java

public class Cat implements Animal {
    private String callSound;
    
    @Override
    public void setCallSound(String sound) {
        this.callSound = sound;
    }

    @Override
    public void call() {
        System.out.println("猫学狗叫：" + callSound);
    }

    @Override
    public void setAction(String action) {
        // 猫不需要学狗的动作
    }

    @Override
    public void action() {
        System.out.println("猫抓老鼠");
    }
    
    public void catchMouse() {
        System.out.println("猫自己会抓老鼠");
    }
}

Dog.java

public class Dog implements Animal {
    private String callSound;
    private String action;
    
    @Override
    public void setCallSound(String sound) {
        this.callSound = sound;
    }

    @Override
    public void call() {
        System.out.println("狗学猫叫：" + callSound);
    }

    @Override
    public void setAction(String action) {
        this.action = action;
    }

    @Override
    public void action() {
        System.out.println("狗学猫抓老鼠：" + action);
    }
    
    public void learnCall() {
        this.setCallSound("喵喵喵");
    }
}

Adapter.java

public class Adapter implements Animal {
    private Animal animal;
    
    public Adapter(Animal animal) {
        this.animal = animal;
    }

    @Override
    public void setCallSound(String sound) {
        animal.setCallSound(sound);
    }

    @Override
    public void call() {
        animal.call();
    }

    @Override
    public void setAction(String action) {
        animal.setAction(action);
    }

    @Override
    public void action() {
        animal.action();
    }
    
    public void learnCall() {
        if (animal instanceof Dog) {
            ((Dog)animal).learnCall();
        }
    }
    
    public void catchMouse() {
        if (animal instanceof Cat) {
            ((Cat)animal).catchMouse();
        }
    }
}

Main.java

public class Main {
    public static void main(String[] args) {
        Cat cat = new Cat();
        Dog dog = new Dog();
        Adapter catAdapter = new Adapter(cat);
        Adapter dogAdapter = new Adapter(dog);
        
        catAdapter.setCallSound("汪汪汪");
        catAdapter.call();
        catAdapter.setAction("捉老鼠");
        catAdapter.action();
        
        System.out.println();
        
        dogAdapter.setCallSound("喵喵喵");
        dogAdapter.call();
        dogAdapter.setAction("抓老鼠");
        dogAdapter.action();
        
        System.out.println();
