У Scanner есть удобный метод hasNextInt, можно сразу узнать без дополнительных проверок возможно ли интерпретировать строку как int

| Bill bill = new Bill(); | ||
| String completion = ""; | ||
| while (completion.compareToIgnoreCase("Завершить") != 0) { |
| bill.addToList(scanner.next()); | ||
| System.out.print("Введите стоимость товара: "); | ||
| input = scanner.next(); | ||
| while (!isValidDouble(input)) { |
