Answer 1

After modifying the StarbuzzCoffee.java

import java.util.*;
public class Main {

   public static void main(String args[]) {
       Scanner sc=new Scanner(System.in);
       Beverage beverage = new Espresso();
       System.out.println(beverage.getDescription()
               + " $" + beverage.cost());
              
       Beverage beverage1 = new Decaf();
       beverage1 = new Soy(beverage1);
       beverage1 = new Mocha(beverage1);
       beverage1 = new Whip(beverage1);
       beverage1 = new Cinnamon(beverage1);
       beverage1 = new Mint(beverage1);
       beverage1 = new Chocolate(beverage1);
       System.out.println(beverage1.getDescription()
               + " $" + beverage1.cost());

       Beverage beverage2 = new DarkRoast();
       beverage2 = new Soy(beverage2);
       beverage2 = new Mocha(beverage2);
       beverage2 = new Whip(beverage2);
       beverage2 = new Cinnamon(beverage2);
       beverage2 = new Mint(beverage2);
       beverage2 = new Chocolate(beverage2);
       System.out.println(beverage2.getDescription()
               + " $" + beverage2.cost());

       beverage2 = new Chocolate(beverage5);
       System.out.println(beverage5.getDescription()
               + " $" + beverage5.cost());
        System.out.println("Coffee types: 1.Decaf Coffee  2.DarkRoast Coffee 3.HouseBlend Coffee 4. Hazelnut coffee 5.caramel Coffee");
        System.out.println("Select the type of coffee you want");
        int choice = sc.nextInt();
        double price=0;
        if (choice==1){
            price= beverage1.cost();
        }
        else if (choice==2){
             price=beverage2.cost();
        }
        else if(choice==3){

        }
        else if(choice==5){
             price=beverage5.cost();
        }
        System.out.println("Do you want to add soy? Y/N");
        char c = sc.next().charAt(0);
                if(c=='y'||c=='Y'){
                    price=price+0.15;
                }
                System.out.println("Do you want to add Mocha? Y/N");
        c = sc.next().charAt(0);
                if(c=='y'||c=='Y'){
                    price=price+0.20;
                }
                System.out.println("Do you want to add Whip? Y/N");
        c = sc.next().charAt(0);
                if(c=='y'||c=='Y'){
                    price=price+0.15;
                }
                System.out.println("Do you want to add Cinnamon? Y/N");
        c = sc.next().charAt(0);
                if(c=='y'||c=='Y'){
                    price=price+0.15;
                }
                System.out.println("Do you want to add Mint? Y/N");
        c = sc.next().charAt(0);
                if(c=='y'||c=='Y'){
                    price=price+0.15;
                }
                System.out.println("Do you want to add Chocolate? Y/N");
        c = sc.next().charAt(0);
                if(c=='y'||c=='Y'){
                    price=price+0.20;
                }
                System.out.println("The total cost your coffee is:"+price);
   }
}
