}
需求说明:
模拟实现愤怒的小鸟,定义鸟叫的接口,定义"嗷嗷叫",“喳喳叫"两种实现类
定义抽象类,“鸟”,将接口定义为鸟的属性,并定义两个子类,“炸弹鸟”,“分裂鸟”
定义测试类,测试"炸弹鸟”,和"分裂鸟" 叫 和 飞 的行为
1.定义一个接口 鸟叫的接口
package com.chen.pojo.DuoTai1;
public interface Shout {
public void shout();
}
2.定义嗷嗷叫的实现类
public class AoShout implements Shout{
String name;
public AoShout(String name) {
this.name = name;
public String getName() {
return name;
public void setName(String name) {
this.name = name;
@Override
public void shout() {
System.out.println(name+"嗷嗷叫,实现Shout接口");
}
3.定义喳喳叫的实现类
public class ZhaShout implements Shout{
String name;
public String getName() {
return name;
public void setName(String name) {
this.name = name;
public ZhaShout(String name) {
this.name = name;
@Override
public void shout() {
System.out.println(name+"喳喳叫,实现Shout接口");
}
4.定义不会叫的实现类
public class NoShout implements Shout{
String name;
public String getName() {
return name;
public void setName(String name) {
this.name = name;
public NoShout(String name) {
this.name = name;
@Override
public void shout() {
System.out.println(name+"不叫,实现Shout接口");
}
5.定义一个抽象类 鸟
public abstract class Brid {
String name;
public String getName() {
return name;
public void setName(String name) {
this.name = name;
private Shout shout;
public Shout getShout() {
return shout;
public void setShout(Shout shout) {
this.shout = shout;
public void fly(){
System.out.println(name+"在Brid抽象父类中飞。。。");
public void shout1(){
shout.shout();
public abstract void hit();
}
6.定义鸟的子类,分裂鸟
public class LieBrid extends Brid{
@Override
public void hit() {
System.out.println(name+"在LieBrid中扔蛋攻击》》》");
}
7.定义鸟的子类,炸弹鸟
public class BoomBrid extends Brid{
@Override
public void hit() {
System.out.println(name+"在BoomBrid中扔蛋攻击》》》");
}
8.定义鸟的子类,肥胖鸟
public class FatBrid extends Brid{
@Override
public void hit() {
System.out.println(name+"在FatBrid中扔蛋攻击》》》");
}
9.定义一个测试类
package PolymorphismAngryBird;
public class BridTest {
public static void main(String[] args) {
Brid brid = null;
Scanner sc = new Scanner(System.in);
System.out.println("请输入你想实例化以下哪种鸟:");
System.out.println("1:肥胖鸟");
System.out.println("2:分裂鸟");
System.out.println("3:爆炸鸟");
int chiose = sc.nextInt();
switch (chiose){
case 1:
brid = new FatBrid();
System.out.println("肥胖鸟实例化成功");
System.out.println("请给小鸟取个名字:");
brid.setName( sc.next());
brid.hit();
brid.fly();
brid.setShout(new NoShout(brid.name));
brid.shout1();
break;
case 2:
brid = new LieBrid();
System.out.println("分裂鸟实例化成功");
System.out.println("请给小鸟取个名字:");
brid.setName( sc.next());
brid.hit();
brid.fly();
brid.setShout(new ZhaShout(brid.name));
brid.shout1();
break;
case 3:
brid = new BoomBrid();
System.out.println("爆炸鸟实例化成功");
System.out.println("请给小鸟取个名字:");
brid.setName( sc.next());
brid.hit();
brid.fly();
brid.setShout(new AoShout(brid.name));
brid.shout1();
break;
}
10.输出的结果
请输入你想实例化以下哪种鸟:
1:肥胖鸟
2:分裂鸟
3:爆炸鸟
肥胖鸟实例化成功
请给小鸟取个名字:
小胖在FatBrid中扔蛋攻击》》》
小胖在Brid抽象父类中飞。。。
小胖不叫,实现Shout接口
