1.将实验五第四题中的四个动物类（鱼类、鸟类、爬行类、昆虫类）的报告类别和天赋，分别用抽象类和接口来完成

abstract class AbstractClass {
	public int id;  //编号
	public StringBuffer name;//名字
	public String type; //类别：鸟类、昆虫类、爬行类和鱼类之一
	abstract public void showType();//在console上秀自己的类别
	abstract public void showTalent();//在console上秀自己的天赋特长
	public void showName()
	{
		System.out.println("My name is "+this.name+", i am from AbstractClass(抽象类)");
	}
}
class Fish extends AbstractClass
{	public Fish(int id,StringBuffer name) 
	{this.id=id;
	this.name=name;
	this.type="fish";
	}

	public void showType()//在console上秀自己的类别
	{
	System.out.println("My ID is "+id+" and I am just an animal, my type is fish");
	}
	public void showTalent()//在console上秀自己的天赋特长
	{
	System.out.println("I am talented at swiming");
	}
	
}
class Bird extends  AbstractClass
{	public Bird(int id,StringBuffer name) 
	{this.id=id;
	this.name=name;
	this.type="bird";
	}

	public void showType()//在console上秀自己的类别
	{
		System.out.println("My ID is "+id+" and I am just an animal, my type is bird");
	}
	public void showTalent()//在console上秀自己的天赋特长
	{
		System.out.println("I am talented at flying");
	}
}	
class Insect extends AbstractClass
{	public Insect(int id,StringBuffer name) 
	{this.id=id;
	this.name=name;
	this.type="insect";
	}

	public void showType()//在console上秀自己的类别
	{
		System.out.println("My ID is "+id+" and I am just an animal, my type is insect");
	}
	public void showTalent()//在console上秀自己的天赋特长
	{

	}
	
}
class Reptile extends  AbstractClass
{	public Reptile(int id,StringBuffer name) 
	{this.id=id;
	this.name=name;
	this.type="reptile";
	}

	public void showType()//在console上秀自己的类别
	{
		System.out.println("My ID is "+id+" and I am just an animal, my type is reptile");
	}
	public void showTalent()//在console上秀自己的天赋特长
	{
		System.out.println("I am talented at crawling");
	}
}
