Question

Stuck on this coding practice. Explain in java please and thank you!

Given two integers as user inputs that represent the number of drinks to buy and the number of bottles to restock, create a VendingMachine object that performs the following operations:

  • Purchases input number of drinks
  • Restocks input number of bottles
  • Reports inventory

The VendingMachine is found in VendingMachine.java. A VendingMachine's initial inventory is 20 drinks.

Ex: If the input is:

5 2

the output is:

Inventory: 17 bottles

given code:

LabProgram.java

 

mport java.util.Scanner;

public class LabProgram {
   public static void main(String[] args) {
      Scanner scnr = new Scanner(System.in);
      
      /* Type your code here. */ 
      
   }
}

VendingMachine.Java (READ ONLY) 

// simulates a simple vending machine with operations to purchase drinks and check inventory.
public class VendingMachine {
   
   // number of bottle in stock
   private int bottles;
   
   // initial inventory is 20
   public VendingMachine(){
      bottles = 20;
   }

   public void purchase(int amount){
      bottles = bottles - amount;
   }
  
   public int getInventory(){
      return bottles;
   }

   public void restock(int amount){
      bottles = bottles + amount;
   }
 
   public void report(){
      System.out.println("Inventory: " + bottles + " bottles");
   }
   
}
