在Java编程语言中,鸟和狼都是动物,它们都可以用代码来描述和模拟。
public abstract class Animal { protected String name; protected int age; public Animal(String name, int age) { this.name = name; this.age = age; } public abstract void move(); public void eat(String food) { System.out.println(name + " is eating " + food); } } public class Bird extends Animal { public Bird(String name, int age) { super(name, age); } @Override public void move() { System.out.println(name + " is flying"); } public void sing() { System.out.println(name + " is singing"); } } public class Wolf extends Animal { public Wolf(String name, int age) { super(name, age); } @Override public void move() { System.out.println(name + " is running"); } public void howl() { System.out.println(name + " is howling"); } }
上述代码定义了一个抽象类Animal和两个子类Bird和Wolf,它们都具有公共的属性和方法,如名称、年龄和移动行为。Bird还有唱歌这个特殊的行为,而Wolf则有嚎叫这个特殊的行为。
通过上述代码,我们可以使用Java语言来模拟和描述鸟和狼这两个动物的行为,让它们在代码中跑起来。
