Question

How to create a constructor that uses parameters from different classes?
I have to create a constructor for the PrefferedCustomer class that takes parameters(name, address,phone number, customer id, mailing list status, purchase amount) but these parameters are in superclasses Person and Customer.
I have to create an object like the example below.......
PreferredCustomer preferredcustomer1 = new PreferredCustomer("John Adams", 
"Los Angeles, CA", "3235331234", 933, true, 400);
System.out.println(preferredcustomer1.toString() + "\n");


public class Person {
    private String name;
    private String address;
    private long phoneNum;

    public Person(String name, String address, long phoneNum) {
        this.name = name;
        this.address = address;
        this.phoneNum = phoneNum;
    }

    public Person(){

    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public long getPhoneNum() {
        return phoneNum;
    }

    public void setPhoneNum(long phoneNum) {
        this.phoneNum = phoneNum;
    }




}

public class Customer extends Person {

    int CustomerNum;
    boolean mailingList;

    public Customer(int customerNum, boolean mailingList) {
        CustomerNum = customerNum;
        this.mailingList = mailingList;
    }
    public Customer(){

    }

    public int getCustomerNum() {
        return CustomerNum;
    }

    public void setCustomerNum(int customerNum) {
        CustomerNum = customerNum;
    }

    public boolean isMailingList() {
        return mailingList;
    }

    public void setMailingList(boolean mailingList) {
        this.mailingList = mailingList;
    }


}

public class PrefferedCustomer extends Customer{

    private int amountOfPurchase;
    private double discount;

    public PrefferedCustomer(Person name,Customer ,int amountOfPurchase) {


        this.amountOfPurchase = amountOfPurchase;
        this.discount = discount;
    }

    public int getAmountOfPurchase() {
        return amountOfPurchase;
    }

    public void setAmountOfPurchase(int amountOfPurchase) {
        this.amountOfPurchase = amountOfPurchase;
    }

    public double getDiscount() {
        return discount;
    }

    public void setDiscount(double discount) {
        this.discount = discount;
    }
}
