Answer 1

import java.util.*;
public class Program
{
public static void main(String[] args) {
HashMap<String,Double> map = new HashMap<>();
map.put("Sabon",21.50);
map.put("Shampoo",5.75);
map.put("Bulad",15.0);
map.put("Noodles",12.0);
map.put("Pan",10.0);
map.put("Sardinas",17.50);
Scanner sc = new Scanner(System.in);
String name = sc.next();
int qty = sc.nextInt();
if(map.get(name) == null){
System.out.println("Product Not Found!");
}else{
double total = map.get(name) * qty;
System.out.println("you will have to pay: "+total);
}
}
}

/*adding cash tendered would be a bad idea to do this here in sololearn since the entry is made only at the beginning*/

Answer 2

Another way to Erlénio.RS presented HashMap, is build own data type. You can see it here:
