F. Ask for the Java source code of the pet store program
//I hope to adopt it, it is not easy to type so many words
1. Problem description
Design a pet store, there can be a variety of pets in the store, try to express this relationship, and request that the corresponding pet information can be searched according to keywords. The required pet information is set by yourself.
1. It can save the information of multiple pets.
2. Pet attributes: name, age, etc.
3. It can realize functions such as pet listing, delisting, and fuzzy query.
Implementation ideas
1. First of all, you need to define a pet class, because there are many kinds of pets, so you need to define an abstract class. This class needs to contain various information about pets, such as: species, name, age, male and female, etc.
2. After you have pets, you need to define a store class to store various pets. This store class can display pet information in the store to meet user needs.
3. To implement the pet’s listing and de-listing operations, it is also necessary to define a listing class and a de-listing class. This class allows pets to be put on and off the shelves for storage in the store.
4. To realize the fuzzy query function, it is necessary to define a query class, which can be displayed by inputting keywords to query the pet information in the store.
5. To implement the appeal function, you also need to define a test class to implement the above operations.
Code implementation:
1.Pet class
package pet store;
public abstract class pet class{
public String species; //species
public String name; //name
public String sex; //male and female
public int age; //age
public pet class() {
}
public pet class(String species,String name,String sex,int age) {
this.species=species;
this.name=name;
this.sex=sex ;
this.age=age;
}
public abstract void pet1();
public void setspecies(String species) {
this.species =species;
}
public String getspecies() {
return species;
}
public void setname(String name) {
this.name=name;
}
public String getname() {
return name;
}
public void setsex(String sex) {
this.sex=sex;
}
public String getsex() {
return sex;
}
public void setage(int age ) {
this.age=age;
}
public int getage() {
return age;
}
}
2. Store class
package pet store;
public class merchant Store class extends Pet class{
public Store class (String species,String name,String sex,int age) {
super(species, name, sex,age);
}
public void pet1() {
System.out.println(“Pet type:”+species+”\tPet name:”+name+”\tPet gender”+sex+”\tPet age”+age+”year”);
}
static store class doug1=new store class(“Golden Retriever”,”Bean”,”male”,1);
static store class doug2=new store class(“sheepdog”,”Flower”, “female”,2);
static store class doug3=new store class(“teddy”,”Mao Mao”,”male”,1);
static store class doug4=new store class(” Erha”,”Dumb”,”Female”,2);
static store class cat1=new store class(“Garfield”,”chubby”,”male”,1);
static store class cat2=new store class(“Persian cat”,”Lingling”,”female”,2);
}
3.Removal class
package pet store;
import java.util.Scanner;
public class remove class{
public static void XJ() {
Scanner scanner = new Scanner(System.in);
System.out.println(“The store has the following pets:”);
Store class.doug1.pet1();
Store class.doug2.pet1();
Store class. doug3.pet1();
Store class.doug4.pet1();
Store class.cat1.pet1();
Store class.cat2.pet1();
System .out.println(“Please select the name of the pet you want to remove”);
String name = scanner.next();
System.out.println(“Hello, you have been removed successfully The name is: “+name+”‘s pet”);
}
}
4. Listing class
package pet store;
import java.util.Scanner;
public class listing class{
public static String species; //kind
public static String name; //name
public static String sex; //male and female
public static int age; //age
public static void SJ() {
Scanner scanner = new Scanner(System.in);
System.out.println(“Please enter the type of pet you want to list:”);
species=scanner.next();
System.out.println(“Please enter the name of the pet you want to list:”);
name=scanner.next();
System.out.println(“Please enter the name you want List the sex of the pet: “);
sex=scanner.next();
System.out.println(“Please enter the age of the pet you want to list:”);
age=scanner .nextInt();
Store class cw=new Store class(species,name,sex,age);
System.out.println(“Congratulations, you have successfully listed:”);
cw.pet1();
System.out.println(“Now this store has:”);
Store class.doug1.pet1();
Store class.doug2.pet1 ();
StoreClass.doug3.pet1();
StoreClass.doug4.pet1();
StoreClass.cat1.pet1();
StoreClass.cat2 .pet1();
cw.pet1();
}
}
5. Query class
package pet store;
import java.util. Scanner;
public class query class{
public static v oid CX() {
Scanner scanner = new Scanner(System.in);
System.out.println(“Hello dear customer, I will provide you with the best service”);
System.out.println(“1: Query pet types in our store\t2: Query pet information in our store”);
int n = scanner.nextInt();
if(n==1) {
System.out.println(“Dear customer, our store currently has: 1. Pet dog\t2, pet cat”);
}
if(n==2) {
System.out.println(“Please input the type of pet you want to query:”);
String name = scanner.next();
if(name.equals(“dog”) ||name.equals(“gou”)) {
System.out.println(“The varieties of “+name+” provided by this store are: “);
Store class.doug1.pet1();
Store class.doug2.pet1();
Store class.doug3.pet1();
Store class.doug4.pet1();
}
else if( name.equals(“cat”)||name.equals(“mao”)) {
System.out.println(“The variety of “+name+” provided by this store is: “);
Store class .cat1.pet1();
Store class.cat2.pet1();
}
else {
System.out.println(“Sorry, we can’t provide you Required pets: “+name);
}
}
}
}
6. Test class
package pet store;
import java.util.Scanner;
public class test class{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.prin tln(“**********Welcome to the pet store online system**********”);
System.out.println(“We will provide you with the most Excellent service, please make the following choices”);
System.out.println(“1: Employee login\t2: Dear customer”);
int i = scanner.nextInt();
if(i==1){
System.out.println(“Hello dear staff, please select the operation you want to do:”);
System.out.println(“1: Put the pet on the shelf\t2: Put the pet on the shelf Take off the shelf”);
int n = scanner.nextInt();
if(n==1) {
//Go to the listing class
The listing class.SJ ();
}
if(n==2) {
//Go to the unlisted class
Unlisted class.XJ();
}
}
if(i==2) {
Query class.CX();
}
}
}
