1、创建动物类

package net.YGQ.p03.t03; public class Animal { private String name; private int age; public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public void speak() { System.out.println(name + "今年" + age + "岁了。"); } public void move() { System.out.println(name + "在动……"); } public void eat() { System.out.println(name + "在吃……"); } @Override public String toString() { return "Animal{" + "name='" + name + ''' + ", age=" + age + '}'; } }

2、继承动物类，创建猫类

package net.YGQ.p03.t03; public class Cat extends Animal { @Override public void move() { System.out.println("猫咪[" + getName() + "]在走路。"); } @Override public void eat() { System.out.println("猫咪[" + getName() + "]爱吃鱼虾。"); } public void play() { System.out.println("猫咪[" + getName() + "]在玩老鼠。"); } }

3、继承动物类，创建狗类

package net.YGQ.p03.t03; public class Dog extends Animal { @Override public void move() { System.out.println("狗崽[" + getName() + "]在蹦跳。"); } @Override public void eat() { System.out.println("狗崽[" + getName() + "]爱吃骨头。"); } public void play() { System.out.println("狗崽[" + getName() + "]在玩飞盘。"); } }

4、继承动物类，创建鸟类

package net.YGQ.p03.t03; public class Bird extends Animal { @Override public void move() { System.out.println("鸟儿[" + getName() + "]在飞翔。"); } @Override public void eat() { System.out.println("鸟儿[" + getName() + "]爱吃小虫。"); } public void play() { System.out.println("鸟儿[" + getName() + "]在玩羽毛。"); } }
