        carlist.add(new Car("Toyota", "Altis", "SJC2456X", 100, 60));
        carlist.add(new Car("Toyota", "Vios", "SJG9523B", 100, 50));

                System.out.print("Enter number of days: ");
                int days = input.nextInt();
                System.out.println("***************Details*****************");
                int cost = (days * s.getRate())   s.getDeposit();
                System.out.println("Deposit  DailyRate  Duration  TotalCost");
                System.out.println(s.getDeposit()   "       "   s.getRate()   "            "   days   "        "   cost);
                System.out.print("Proceed to rent?( y/n ): ");
                String dec = input.next();
                if (dec.equals("y")) {
                    System.out.println("Enter Customer Name: ");
                    String name = input.next();

                    System.out.println(name   "   "   num   "   "   model
                              "   "   s.getRegNo()   "   "   days   "   "   cost);
                    System.out.println("Serving Next Customer ");
                } else if (dec.equals("n")) {
                    System.out.println("Serving Next Customer: ");
                }
            }
        }
    }
}

thats the full code

i already tried changing it to "object" but it just gives me more errors so please help

CodePudding user response：

An easy fix for your problem is to create the list like this:

List<Car> carlist = new ArrayList<>();

If you can't do that, then you could use

for (Car s : (List<Car>)carlist) {
