Answer 1

Answer:

import java.util.Scanner;

class Main {

 public static void main (String args[])

 {

   Scanner input = new Scanner(System.in);

   VendingMachine machine = new VendingMachine(20);

   System.out.print("Enter nr to purchase: ");

   int nrPurchased = input.nextInt();

   System.out.print("Enter nr to re-stock: ");

   int nrRestock = input.nextInt();

   machine.Transaction(nrPurchased, nrRestock);

   input.close();

 }

}

class VendingMachine {

 private int inventory;

 public VendingMachine(int initialInventory) {

   inventory = initialInventory;

 }

 public void Transaction(int nrToBuy, int nrToRestock) {

   inventory += nrToRestock - nrToBuy;

   System.out.printf("Inventory: %d bottles.\n", inventory);

 }

}
