Question

I have an abstract class Employee, and based on that, I created the following subclasses:

FulltimeEmployee
PartTimeEmployee
Salesman

as well as one standalone class, Orders.

I use the Orders class to "describe the salesman" by sending an array of orders in the Salesman constructor:

public Salesman(String firstname, String lastname,int code, String address,
                String city,int tk,int phone,String email,int deptcode,int card,
                double hours,String cat,int orderno,double salary,
                Orders[] order){
 super(  firstname, lastname, code,  address, city, tk, phone, email, deptcode,
         card, hours, cat );
 this.orderno=orderno;
 
 setBaseSalary( salary );
 getSalary(orders);
 /////////////////

 }

Later, I use that array to calculate the bonus a salesman gets, depending on the amount of sales he makes.

In main, I created an array of type Employee:

Employee employees[] = new Employee[ 7 ];
   employees[ 0 ] = salary1;
   employees[ 1 ] = salary2;
   employees[ 2 ] = salary3;
   employees[ 3 ] = partt1;
   employees[ 4 ] = partt2;
   employees[ 5 ] = sales1;
   employees[ 6 ] = sales;

where each row is a different type of employee (salary = full-time, partt = part-time, and sales = salesman).

My problem is that I want to print the orders of each salesman using the employees array.
What I’ve done so far is

for (int i=5;i<employees.length;i++){
              System.out.printf("Orders of Salesman: %S %S",
                  employees[i].getName(),employees[i].getSurname());
              System.out.printf(" Total amount(money) from orders: %,.0f ",
                  employees[i].earnings());
              int j=0;
              ((Salesman)employees[i]).getOrderNo(arr) ;
              //((Orders)employees[i]).getOrderNo();
              System.out.printf("ordernumber: %d  orderdate:%s  description: %s
                  order amount(money): %,.0f\n ");
                 
           }

The problem comes here:

System.out.printf("ordernumber: %d orderdate:%s description: %s order amount(money): %,.0f\n ");

How do I access the orders array inside of the Salesman object on employees array?
I have tried casting, but it won’t work because Orders is not a subclass of Employee.

I need it to print, for example,

Orders of Salesman: john koun

Total amount of orders: 13000
Orders per Salesman

Order number: 1 order date: 10/2/2010 description: machinery sale order amount: 12000

Order number: 2 order date: 20/2/2010 description: sales of parts order amount: 1000

Answer 1

your Salesman constructor accepts an Order[] orders but it doesn’t look like you keep a reference to it anywhere (unless you do that in getSalary or in the commented out portion).

You will need to add something like

this.orders = orders;

in your Salesman constructor so you can refer to the array as a field/property of the Salesman object.

Typically you should use the Bean pattern whereby each field has a getter/setter method:

public Order[] getOrders(){
    return orders;
}

public void setOrders(Order[] orders){
    this.orders=orders;
}

then in your constructor add setOrders(orders);

and then in your debug/output code add:

Salesman salesman = (Salesman) employees[i];
for (Order order : salesman.getOrders())
    System.out.println(order); // i don't know what fields order has!
