作者：互联网
Java练习之宠物管理系统
该宠物管理具有功能：
- 保存大量宠物信息
- 查看所有的宠物
- 通过名字查看某个宠物
- 输入宠物信息，录入系统中
- 修改系统中的宠物信息
- 删除宠物的信息
- 按年龄或价格进行排序
代码如下：
Pet类
public class Pet {
private String name;
private String gender;
private String type;
private int age;
private int price;
private int weight;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public int getPrice() {
return price;
}
public void setPrice(int price) {
this.price = price;
}
public int getWeight() {
return weight;
}
public void setWeight(int weight) {
this.weight = weight;
}
public Pet() {
}
public Pet(String name, String gender, String type, int age, int price, int weight) {
this.name = name;
this.gender = gender;
this.type = type;
this.age = age;
this.price = price;
this.weight = weight;
}
public void play(){
System.out.printf("宠物：%s\t\t性别：%s\t\t类型：%s\t\t年龄：%d\t\t价格：%d\t\t重量：%d\n",
this.name,this.gender,this.type,this.age,this.price,this.weight);
}
}
PetManage接口类：
import java.util.ArrayList;
public interface PetManage {
/**
* 显示所有宠物的信息
*/
void showAllPets(ArrayList<Pet> pets);
/**
* 按宠物的名字查找宠物
* @param name
* @param pets
*/
void findPetByName(String name, ArrayList<Pet> pets);
/**
* 输入宠物信息
* @return
*/
Pet inputPetInfo();
/**
* 添加宠物
* @param pet
* @param pets
*/
void addPet(Pet pet, ArrayList<Pet> pets);
/**
* 按名字修改宠物
* @param name
* @param pets
*/
void updatePetByName(String name,ArrayList<Pet> pets);
/**
* 删除宠物
* @param name
* @param pets
*/
void removePetByName(String name,ArrayList<Pet> pets);
/**
* 按年龄排序
* @param pets
*/
void sortByAge(ArrayList<Pet> pets);
/**
* 按价格排序
* @param pets
*/
void sortByPrice(ArrayList<Pet> pets);
}
PetShop类：
import java.util.ArrayList;
import java.util.Collections;
import java.util.Scanner;
public class PetShop implements PetManage{

}
@Override
public void sortByPrice(ArrayList<Pet> pets) {
Collections.sort(pets,(o1,o2)->o1.getPrice()-o2.getPrice());
}
}
PetShopApp类：
import java.util.ArrayList;
import java.util.Scanner;
public class PetShopApp {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
PetShop petshop = new PetShop();
ArrayList<Pet> pets = new ArrayList<>();
pets.add(new Pet("white","M","dog",1,2000,2));

pets.add(new Pet("blue","M","cat",1,1600,4));
pets.add(new Pet("flower","F","cat",3,5000,3));
pets.add(new Pet("red","F","cat",1,4600,1));
for(;;){
System.out.println("--------------------欢迎使用宠物管理系统--------------------");
System.out.println("请选择执行的操作： 1.查看所有宠物 2.添加宠物 3.修改宠物 4.查找宠物 " +
"5.删除宠物 6.按年龄排序 7.按价格排序 其他：退出");
int op = scanner.nextInt();
switch(op){
case 1:
petshop.showAllPets(pets);
break;
case 2:
Pet pet = petshop.inputPetInfo();
petshop.addPet(pet, pets);
break;
case 3:
System.out.println("请输入要修改的宠物名");
String petName = scanner.next();
petshop.updatePetByName(petName,pets);
break;
case 4:
System.out.println("请输入要查找的宠物名");
String searchName = scanner.next();
petshop.findPetByName(searchName, pets);
break;
case 5:
System.out.println("请输入要删除的宠物名");
String deleteName = scanner.next();
petshop.removePetByName(deleteName,pets);
break;
case 6:
petshop.sortByAge(pets);
petshop.showAllPets(pets);
break;
case 7:
petshop.sortByPrice(pets);
petshop.showAllPets(pets);
break;
default: return;
}
}
}
}
