    Default problem with an assignement: creating collections class and use them

    Well, in my java project , I need to create using netbeans a program similar to the Amazon website, well I post you the link so you can see all of it, it can help you: (c) CJoint.com, 2012

    Well I need to make a menu in which the user can register as a member, modify profile etc, browse for books and view their data,etc..
    Here is my code from the class Member:
    package amazonapplication;
    import java.util.Scanner;
    /**
     *This class describes a Member
     * @author 
     */
    public class Member {
        private String username;
        private String password;
       /**
        * 
        * @param user name as a string
        * @param pass password as a string
        */ 
        public Member(String user, String pass ){ 
            username=user;
           password=pass;
        }
     
        /**
         * Setter of Password
         * @param password the password to set
         */
        public void setPassword(String password){ 
           this.password=password;
        }
        /**
         * Setter of Username
         * @param username the username to set
         */
        public void setUsername(String username){
            this.username=username;
        }
        /**
         * Getter of Username
         * @return the username
         */
        public String getUsername(){ // get method for username
            return username;
        }
        /**
         * Getter of Password
         * @return the password
         */
        public String getPassword(){ // get method for password
            return password;
        }
        /**
         * Method used to change current password
         * @param password current password to change
         * @param newpass  new password to set
         * @return boolean change of password successful or not
         */
        public boolean changePass(String password, String newpass){
            if(this.getPassword().equals(password)){
                this.setPassword(newpass);
                    return (true);
            }
            else return (false);
        }
    /**
     * Method used to set new password if old one is lost/forgotten
     * @param username member's username
     * @param newpass memeber's new password
     * @return boolean: procedure successful or not 
     */
        public boolean forgotpass(String username, String newpass){
            if(this.username.equals(username)){
                this.setPassword(newpass);
                return (true);
     
            }
            else return (false);
     
        }
         /**
         * Method used to authenticate user
         * @param username name as string
         * @param password password as string
         * @return boolean: authentification successful or not
         */
        public void authenticate  (String username, String password)throws PassException{
            if(this.username.equals(username) && this.password.equals(password))
               System.out.println("Authentification Successful!");
     
            else throw new PassException ();
     
     
        }
        /**
         * Prints member information
         * @return String to print 
         */
        @Override
        public String toString(){
            return "username is:"+this.username+
                   "\npassword is:"+this.password;
        }
     
    }
    And here is my code the class MemberList(not complete yet, i don't know how to do save and load behaviors)
    /*
     * To change this template, choose Tools | Templates
     * and open the template in the editor.
     */
    package amazonapplication;
    import java.util.ArrayList;
    import java.util.Collections;
    import java.util.Comparator;
    import java.util.LinkedList;
    import java.util.List;
    import java.util.ListIterator;
    /**
     *
     * @author
     */
    public class MemberList {
     
        List<Member> members;
        public MemberList(){
            this.members=new LinkedList<>();
        }
        public boolean addmember(Member memb){
            return members.add(memb);
        }
         public boolean removeMember(Member memb) {
            return members.remove(memb);
    }
     
    }
    Well now that I have coded those classes, I should use them for my main
    But I don't know how, in my main, I can manage when a user wants to register or do something else from the menu. Does it have a relation with associations ? Its said in my assignement: Finish the implementation of the class Member, a member has an association with OrderList.
    Well I am lost
