Explanation / Answer

public class Orders
{
private Srting name ;
private Srting purchaseDate;

public Orders()
{
name = 0;
purchaseDate = 0 ;
}

public Orders(String g, String p)
{
name = g;
purchaseDate = p;
}

public void display()
{
System.out.print(name + " ");
}
}

public class Delievery extends Orders

{

private Srting address ;
private Srting zipcode;

public Delievery()
{
address = 0;
zipcode = 0 ;
}

public Delievery(String a, String z)
{
address = a;
zipcode = z;
}
public void display()
{
System.out.print(zipcode + " ");
}
}

public class Product extends Delievery

{

private Srting productName ;
private int Item_number;

public Product()
{
productName = 0;
Item_number = 0 ;
}

public Product(String pro, String i)
{
productName = pro;
Item_number = i;
}

public void display()
{
System.out.print(productName + " ");
}
}

public class Test
{
public static void main(String args[])
{
    Orders ord = new Orders();        // Creates object of order class
    Delievery del = new Delievery();   // Creates object of Delievery
    Product Pr = new Product();       // // Creates object of product class
  
       ord.display()
       del.display();
       Pr.display();
