Java基于接口实现模拟动物声音代码实例

(1)编写接口Animal (Animal.java)

public interface Animal{

public abstract void cry();

public abstract String getAnimalName();

}

(2)编写模拟类Simulator (Simulator.java)

public class Simulator {

public void playSound(Animal animal) {

System.out.print("正在播放模拟" + animal.getAnimalName() +"的声音:");

animal.cry();

}

}

(3)编写Dog类和Cat类 (Dog.java、Cat.java)

Dog类:

public class Dog implements Animal{

public void cry(){

System.out.println("汪汪汪");

}

public String getAnimalName(){

return "狗";

}

}

Cat类:

public class Cat implements Animal{

public void cry(){

System.out.println("喵喵喵");

}

public String getAnimalName(){

return "猫";

}

}

(4)编写主类Application (Application.java)

public class Application{

public static void main(String[] args) {

Simulator simulator = new Simulator();

simulator.playSound(new Dog());

simulator.playSound(new Cat());

}

}
