编写一个Animal类，具有属性：种类；具有功能：吃、睡。定义其子类Fish

package zhongqiuzuoye;

public class Animal {
    
    //属性
    
    private String type;

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }
    
    //功能
    public void eat()
    {
    }
    public void sleep()
    {
    }
    
    

}

package zhongqiuzuoye;

public class Fish extends Animal{
    
    public void eat()
    {
        System.out.println(getType()+" 吃");
    }
    public void sleep()
    {
        System.out.println(getType()+" 睡");
    }

}

package zhongqiuzuoye;

public class Dog extends Animal{
    
    public void eat()
    {
        System.out.println(getType()+"吃");
    }
    public void sleep()
    {
        System.out.println(getType()+"睡");
    }

}

package zhongqiuzuoye;

public class TestAnamal {
    
    public static void main(String[] args) {
        // TODO 自动生成的方法存根
    
    Fish f=new Fish();
    f.setType("鱼");
    f.eat();
    f.sleep();
    
    Dog d=new Dog();
    d.setType("狗");
    d.eat();
    d.sleep();
    
    

    }
