(1)編寫接口Animal (Animal.java)

public interface Animal{ public abstract void cry(); public abstract String getAnimalName();}

(2)編寫模擬類Simulator (Simulator.java)

public class Simulator { public void playSound(Animal animal) { System.out.print('正在播放模擬' + animal.getAnimalName() +'的聲音：'); animal.cry(); }}

(3)編寫Dog類和Cat類 (Dog.java、Cat.java)

Dog類：

public class Dog implements Animal{ public void cry(){ System.out.println('汪汪汪'); } public String getAnimalName(){ return '狗'; }}

Cat類：

public class Cat implements Animal{ public void cry(){ System.out.println('喵喵喵'); } public String getAnimalName(){ return '貓'; }}

(4)編寫主類Application (Application.java)

public class Application{ public static void main(String[] args) { Simulator simulator = new Simulator(); simulator.playSound(new Dog()); simulator.playSound(new Cat()); }}
