Java Case Example Commodity inventory management system

Today, according to the code of the teacher to read and write a product inventory management system:

The code is as follows

/*
Achieve inventory management of commodities
Function:
1. Display User Selection Function list
2. Perform different operations according to the selected function number
A. Show all Inventory
B. Modifying inventory quantities

Analysis:
1. Display user list:
Output statement, user input, select function serial number
2. Depending on the selection, call different methods
Switch statement
Case 1 2 3
A Display Inventory
Will store an array of goods, traverse
B Modify Inventory

To modify all inventory quantities
*/
Guide Package
Import Java.util.Scanner;
public class shopping{
public static void Main (string[] args) {
Depositing basic data information into an array
String[] Pinpai = {"Macbookair", "Thinkpa450", "EatpadT897"};
double[] size = {13.3,15.6,25.6};
Double[] Price = {2567.9,4562.8,9999.6};
Int[] count = {0,0,0};
while (true) {
int choose = Choosefunction ();
Switch (choose) {
View inventory List
Case 1:checkbox (Pinpai,size,price,count);
Break
Modifying inventory data
Case 2:update (Pinpai,count);
Break
Case 3:return;
DEFAULT:SYSTEM.OUT.PRINTLN ("incorrect input");
}
}
}
Show access to the action list interface
public static int choosefunction () {
System.out.println ("----------Inventory Management----------");
System.out.println ("1. View inventory list");
System.out.println ("2. Change the quantity of goods in stock");
System.out.println ("3. Exit");
System.out.println ("Please enter the number of actions to be performed:");
Receiving operation signal from user input
Scanner sc = new Scanner (system.in);
int choosenumber = Sc.nextint ();
Returns the operation signal entered by the user
return choosenumber;
}
View the Inventory List interface
public static void CheckBox (string[] pinpai,double[] size,double[] price,int[] count) {
System.out.println ("----------Store stock list----------");
SYSTEM.OUT.PRINTLN ("Brand model size price Stock Number");
Double totalprice = 0.0;
int totalcount = 0;
for (int i=0;i<pinpai.length;i++) {
System.out.println (pinpai[i]+ "" +size[i]+ "" +price[i]+ "" +count[i]);
Totalprice + = Price[i];
TotalCount + = Count[i];
}
SYSTEM.OUT.PRINTLN ("Total number of stocks" +totalcount);
System.out.println ("The total amount of commodity inventory is" +totalprice);
}
Modify the inventory information interface
public static void UpDate (string[] pinpai,int[] count) {
Scanner sc = new Scanner (system.in);
for (int i=0;i<pinpai.length;i++) {
System.out.println ("Please enter the stock number of the brand" +pinpai[i]+ ");
int n = sc.nextint ();
Count[i] = n;
}
}
}
