本文实例为大家分享了Java实现宠物商店管理的具体代码，供大家参考，具体内容如下

第一种实现方式：抽象类和对象数组

public abstract class AbstractPet //定义宠物模板

{

private String name; //名称

private String color; //颜色

private int age; //年龄

public AbstractPet(){}

public AbstractPet(String name, String color, int age){

this.setName(name);

this.setColor(color);

this.setAge(age);

}

public String getName(){

return this.name;

}

public String getColor(){

return this.color;

}

public int getAge(){

return this.age;

}

public void setName(String name){

this.name = name;

}

public void setColor(String color){

this.color = color;

}

public void setAge(int age){

if (age > 0)

{

this.age = age;

}else{

this.age = 1;

}

}

//定义抽象方法

public abstract void printInfo(); //自我介绍

}

public class Dog extends AbstractPet

{

public Dog(String name, String color, int age){

super(name, color, age);

}

//实现抽象方法

public void printInfo(){ //自我介绍

System.out.println("狗： " + super.getName() + ",年龄 " + super.getAge() + "岁，颜色：" + super.getColor());

}

}

public class Cat extends AbstractPet

{

public Cat(String name, String color, int age){

super(name, color, age);

}

//实现抽象方法

public void printInfo(){ //自我介绍

System.out.println("狗： " + super.getName() + ",年龄 " + super.getAge() + "岁，颜色：" + super.getColor());

}

}

public class PetShop

{

private AbstractPet[] pets;

private int foot; //定义下标

public PetShop(int len){ //宠物数量由用户确定

if (len > 0)

{

this.pets = new AbstractPet[len];

}else{

this.pets = new AbstractPet[1];

}

}

//添加宠物的方法

public boolean add(AbstractPet pet){

if (this.foot < this.pets.length)

{

this.pets[foot] = pet;

this.foot ++;

return true;

}else{

return false;

}

}

//定义查询宠物的方法[提供按照种类查询和按照姓名查询两种方法]

public AbstractPet[] search(String keyword){

int n = 0; //定义查询到的宠物数量

AbstractPet[] searchPets = null;

for (int i = 0; i < this.pets.length; i++)

{

if (this.pets[i] != null)

{

if (this.pets[i].getName().indexOf(keyword) != -1 || this.pets[i].getColor().indexOf(keyword) != -1)

{

n++;

}

}

}

searchPets = new AbstractPet[n];

n = 0;

for (int i = 0; i < this.pets.length; i++)

{

if (this.pets[i] != null)

{

if (this.pets[i].getName().indexOf(keyword) != -1 || this.pets[i].getColor().indexOf(keyword) != -1)

{

searchPets[n] = this.pets[i];

n ++;

}

}

}

return searchPets;

}

}

public class testPetShop

{

public static void main(String[] args){

PetShop p = new PetShop(5);

p.add(new Dog("狗1", "黑色的", 3));

p.add(new Dog("狗2", "红色的", 2));

p.add(new Cat("猫1", "褐色的", 3));

p.add(new Cat("猫2", "黄色的", 3));

p.add(new Cat("猫3", "黑色的", 5));

p.add(new Dog("狗3", "棕色的", 4));

print(p.search("黑"));

}

public static void print(AbstractPet pets[]){

for (int i = 0; i < pets.length; i++)

{

if (pets[i] != null)

{

pets[i].printInfo();

}

}

}

}

第二种实现方式：接口和对象数组

interface IPet

{

String getName(); //取得宠物姓名

String getColor(); //取得宠物颜色

int getAge(); //取得宠物年龄

void show(); //显示宠物信息

}

public class Dog implements IPet

{

private String name;

private String color;

private int age;

public Dog(String name, String color, int age){

this.setName(name);

this.setColor(color);

this.setAge(age);

}

public String getName(){

return this.name;

}

public String getColor(){

return this.color;

}

public int getAge(){

return this.age;

}

public void setName(String name){

this.name = name;

}

public void setColor(String color){

this.color = color;

}

public void setAge(int age){

if (age < 0 || age > 50)

{

this.age = 1; //默认值

}else{

this.age = age;

}

}

public void show(){

System.out.println(this.toString());

}

public String toString(){

return "狗：" + this.getName() + " " + this.getColor() + " " + this.getAge();

}

}

public class Cat implements IPet

{

private String name;

private String color;

private int age;

public Cat(String name, String color, int age){

this.setName(name);

this.setColor(color);

this.setAge(age);

}

public String getName(){

return this.name;

}

public String getColor(){

return this.color;

}

public int getAge(){

return this.age;

}

public void setName(String name){

this.name = name;

}

public void setColor(String color){

this.color = color;

}

public void setAge(int age){

if (age < 0 || age > 50)

{

this.age = 1; //默认值

}else{

this.age = age;

}

}

public void show(){

System.out.println(this.toString());

}

public String toString(){

return "猫：" + this.getName() + " " + this.getColor() + " " + this.getAge();

}

}

public class PetShop

{

private IPet[] pets;

private int foot;

public PetShop(int len){ //宠物店的宠物数量由用户决定

if (len > 0)

{

pets = new IPet[len];

}else{

pets = new IPet[1]; //默认最小数量为1

}

}

public boolean add(IPet pet){

if (this.foot < this.pets.length)

{

this.pets[this.foot] = pet;

this.foot ++;

return true;

}else{

return false;

}

}

public IPet[] search(String keyword){

//定义一个新的宠物对象数组，用来存储符合查询条件的宠物

IPet[] resultPet = null; //不确定数量，要通过循环得到

int count = 0; //用来存储符合查询条件的宠物数量

for (int i = 0; i < this.pets.length; i++)

{

if (this.pets[i] != null)

{

if (this.pets[i].getName().indexOf(keyword) != -1 || this.pets[i].getColor().indexOf(keyword) != -1)

{

count ++;

}

}

}

resultPet = new IPet[count];

int n = 0;

for (int i = 0; i < this.pets.length; i++)

{

if (this.pets[i] != null)

{

if (this.pets[i].getName().indexOf(keyword) != -1 || this.pets[i].getColor().indexOf(keyword) != -1)

{

resultPet[n] = this.pets[i];

n ++;

}

}

}

return resultPet;

}

}

public class TestPetShop

{

public static void main(String[] args){

//创建一个宠物商店

PetShop ps = new PetShop(7); //假设可以放置5只宠物

ps.add(new Dog("旺旺", "黑色的",4));

ps.add(new Dog("旺财", "白色的",6));

ps.add(new Dog("小黑", "黄色的",3));

ps.add(new Cat("波波", "褐色的",7));

ps.add(new Cat("咪咪", "黑色的",8));

ps.add(new Cat("小云", "灰色的",2));

ps.add(new Dog("仔仔", "黄色的",5));

print(ps.search("色"));

}

public static void print(IPet[] pet){

for (int i = 0; i < pet.length; i++)

{

if (pet[i] != null)

{

pet[i].show();

}

}

}

}
