说明:涉及到继承,抽象类,虚方法,接口等知识点
鸟类都有翅膀,
鸟类都会吃,但吃的食物不一样
鸟类都会叫,虽然叫声不一样,喜鹊,燕子,麻雀,感觉都是叽叽喳喳的.程序员中的世界就是讲儿.
鸟类中,麻雀会飞,喜鹊会飞和鸵鸟不会飞
鸟类中,麻雀,喜鹊都是"叽叽喳喳"的叫,鸵鸟"哦哦"(当然我没有听过,也懒得去查,主要矛盾于次要矛盾)
另外飞机也会飞
定义一个父类-鸟类(属性:翅膀;方法:吃;虚方法:叫声)
定义一种能力(接口IFlyable)
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace Bird { public interface IFly { void Fly(); } }
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace Bird { public abstract class Bird { //定义字段--翅膀 private string wing; //根据字段生成属性 public abstract string Wing { set; get; } //定义抽象方法--吃 public abstract void Eat(); //定义虚方法 public virtual void Sing() { Console.WriteLine("叽叽渣渣"); } } }
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace Bird { public class Sparrow:Bird,IFly { public override void Eat() { Console.WriteLine("我是麻雀,我爱吃人类的粮食"); } public void Fly() { Console.WriteLine("我会飞"); } private string wing; public override string Wing { get { return wing; } set { wing = "麻雀的翅膀"; } } } }
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace Bird { class Ostrich:Bird { private string wing; public override string Wing { get { return wing; } set { wing = "鸵鸟的翅膀"; } } public override void Eat() { Console.WriteLine("我是鸵鸟,我吃人"); } public override void Sing() { Console.WriteLine("哦!哦!"); } } }
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace Bird { public class Pie:Bird,IFly { private string wing; public override string Wing { get { return wing; } set { wing = "xique的翅膀"; } } public override void Eat() { Console.WriteLine("我是喜鹊,谷类和虫子"); } public void Fly() { Console.WriteLine("我是喜鹊,我会飞!"); } } }
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace Bird { class Program { static void Main(string[] args) { Bird[] birds = { new Sparrow (),new Ostrich(),new Pie()}; foreach (Bird item in birds) { Console.WriteLine(item.Wing); item.Eat(); item.Sing(); } Sparrow sp = new Sparrow (); Pie p = new Pie(); sp.Fly(); p.Fly(); Console.Read(); } } }
