Dont understand what to write.. :/

any help is appreciated! :)

This is for an assignment, its quite basic stuff as were new to it and i went through the practise stuff in the book so i thought id get it but im stuck whenn it comes to this work, Grr!

ok so the questions are;
"2.1 Add an Order class to your project to store the following information about an Order: the Order's reference number, the customer's name , a description and total cost. In addition, the class also stores the order's call-in time and the delivered time (all of type Time).

2.2 Write a constructor which sets the order reference number, customer name, description, total cost and call-in time from suitable formal parameters. Call-in time should be represented by two formal parameters of type int which are passed as actual parameters to a Time constructor. The delivered time should initially be set to null."

Im having problems with making this "Order" class, i get confused where the two classes mix :/

this is some of the time class;

Code Java:

---

public class Time
{
    //fields
    private int hour;
 
    private int minute;
 
 
    //constructor
    public Time ()
    {
        hour = 0;
        minute = 0;
    }
 
   //method
private void setHour(int newHour)
    {
        if ((newHour >= 0) & (newHour < 24)) {
            hour = newHour;
        }
        else{
        hour=0;
    }
//##more methods down here##
}

---

and well heres what ivei done in the "Order" class which im supposed to be doing now

Code Java:

---

public class Order
{
    // 2.1 - fields
    private int orderNumber;
    private String customerName;
    private String description;
    private int totalCost;
    private Time callInTime;
    private Time deliveredTime;
 
    //2.2 - constructor
    public Order (int newOrderNumber, String newCustomerName, String newDescription, int newTotalCost )
    {
        orderNumber = newOrderNumber;
        customerName = newCustomerName;
        description = newDescription;
        totalCost = newTotalCost;
        callInTime = ;
        deliveredTime = ;
 
    }

thanks for any help
