Text User Interface, can't get a method which adds a customer to work

your (commented-out) method call is wrong

Customer customer = new Customer(fName, lName, acctNumber, street, town, postcode);
//customerList.addCustomer = new Customer(fName, lName, acctNumber, street, town, postcode);

This is not compilable!
customerList.addCustomer(new Customer.......));
Passing Information to a Method or a Constructor (The Java™ Tutorials > Learning the Java Language > Classes and Objects)

and it should be working :)

works like a treat - many thanks eRaaaa

-
this isssignment i'm having a bit of trouble with

i'm given the class called HW4CustomerList, i have to make a Text Based User Interface
the class (below) CustomerTUI contains a method called addCustomer which adds a new object to an arraylist - i'm not particularly sure what is wribg with it

The class specification says that I cannot take any parameters (i.e. a no-args method). we have used the BlueJ 'method box' to interact with objects and put them in array lists, I do not know if this can be used in this particular instance.

below is my CustomerTUI, HW4CustomerList and Customer classes


CustomerTUI class

import java.util.Scanner;

/**
 * Provides a text based user interface application to be used to manage the use of HW4CustomerList

    myScanner = new Scanner(System.in);
  }

  public void menu() {
    int command = -1;
    while (command != 0) {
      displayMenu();
      command = getCommand();
      execute(command);
    }
  }

  /**

   * @param details of the customer to add
   */
  private void addCustomer() {
    Scanner myScanner = new Scanner(System.in);

    System.out.println("Enter the first name of the Customer ");
    String fName = myScanner.nextLine();

    System.out.println("Enter the last name of the Customer");
    String lName = myScanner.nextLine();

    System.out.println("Enter the account number of the Customer");
    String acctNumber = myScanner.nextLine();

    System.out.println("Enter street name of the Customer's address: ");
    String street = myScanner.nextLine();

    System.out.println("Enter the town name of the Customer's address: ");
    String town = myScanner.nextLine();

    System.out.println("Enter post code of the Customer's address: ");
