I understand I somehow have to store Username and Picture to a file? But then how will I be able to call the file in the login screen?

Do I need 3 Arraylists? One for user one for picture one for ID or can I just have one for ID that stores the relation with the picture and username

Ok, thnx for the replies aye. To be honest this doesnt even need security, all it really needs is different files stored for different userz.

I don't want to create a database so I like the flat txt file idea:-| .

Ill read through your comments and see if I can code this.
1. Great, just use java.util.Properties class and things would be even easier than C++. Store the data as "username=pictID" in file.
2. For storing the username vs. ID mapping use HashTable/Map.
3. The pictures: I don't know why you need to store any information abt them at all. See my previous posts. They're static info and can be just kept to the UI component. Don't de/serialize them.

I really appreciate you helping me. I really got to research how to store stuff in files. Im reading documentation on properties at the moment.

So I should use store?

and then load to login?

Once your login page comes, the user would type a username in the control u're using for username, also he'll select/click the picture he wants, on this click you set passWord (as you've coded).
On click of the create account button you just add this username password combination to your HashMap object.
When you're exiting from the process, you serialize (write) the HashMap to a flat file using Properties class (just copy all data from HashMap to Properties class and use it's method to write to file).
At next startup of your process you'll have this process so in main() or somewhere during initialization you create Properties object using name of the the file to which you had serialized, Properties class will read all data.
Now you copy this data from Properties file to HashMap and you're back in business.

Your AccountInfo class would not be required. HashMap that I refer to in my previous post is the one that'll hold username-password combination instead of AccountInfo.

Wow you make it seem so easy. Just add Username and Password to hashmap aye.


java Syntax (Toggle Plain Text) 
  1.  
  2. private HashMap userInformation;
  3.  
  4.  
  5. //createAccountBtn pressed
  6.     createAccountBtn.addActionListener(new ActionListener(){
  7.       public void actionPerformed(ActionEvent e) {
  8.         userName = userNameInput.getText();
  9.  
  10.  
  11. //userNameInput.setText(userName);
  12.  
  13.         userBox.addItem(userName);
  14.  
  15.  
  16.         //AccountInfo.aUserID.add(UserID);
  17.  
  18.         //userID = userName + passWord;
  19.         //userIDs.add(userID);
  20.  
  21.         userInformation.put(userName,passWord);
  22.         //userName = null;
  23.         //passWord = null;
  24.  
  25.       }
  26.     });

Thanks for you help once again. I don't thing you can explain it any simpler. I will make sure to listen to what you said but I right now I really gotta understand hashmaps better .

>> So I should use store?

Yes.
Overall flow would be:
  • From main() you create your UI elements.
  • Add all actionListners().
  • Create the Properties object and call load() with name of the file that you used for storing the data (in last run).
  • Copy all data from this Properties object to a HashMap.
  • On click of one of the pictures you set the password variable (as you're doing).
  • On click of create account button, pickup the username/password and see if it's already existing in the HashMap. If yes, it's an error.
  • On click of Login button pickup the username/password and see if user name is already existing in the HashMap. If not it's an error, if yes see that password (ID) matches.
  • At the end before exiting from main(), copy all data from HashMap to a new Properties object and call store() with the file name.
