Answer 1

here is the method:
//add member
  public void addMember() {
    String output,firstName,secondName,address1,address2,phoneNumberAsString;
    long phoneNumber;
    boolean isMember=true;
    this.memberCounter++;
    Player temp;
    //create HashMap
    HashMap memberList = new HashMap();
    output="Squash Court Booking System \n";
    output=output+"Enter Details \n\n";
    firstName=askUser("Enter First Name: ");
    secondName=askUser("Enter Second Name: ");
    address1=askUser("Enter Street Name and Number: ");
    address2=askUser("Enter Town: ");
    phoneNumberAsString=askUser("Enter Phone Number: ");
    phoneNumber=Long.parseLong(phoneNumberAsString);
    Player p = new Player(firstName,secondName,address1,address2,phoneNumber,isMember);
    //place member into HashMap
    memberList.put(new Integer(memberCounter),p);
    //JOptionPane.showMessageDialog(null,"Membercounter="+memberCounter,"Test",JOptionPane.INFORMATION_MESSAGE);
    //create iterator
    Iterator members = memberList.values().iterator();
    //create output
    output="";
    while(members.hasNext()) {
      temp = (Player)members.next();
      output=output + temp.getFirstName() + " ";
      output=output + temp.getSecondName() + "\n";
      output=output + temp.getAddress1() + "\n";
      output=output + temp.getAddress2() + "\n";
      output= output + temp.getPhoneNumber() + "\n";
      output= output + temp.getIsMember();
    //display message
    JOptionPane.showMessageDialog(null,output,"Member Listings",JOptionPane.INFORMATION_MESSAGE);
  }//end addMemberOn running this, no matter how many details are input, the HashMap only gives me the first one back....
Any ideas?
