Hello. I'm creating a game where people can set up an account. Their registration information includes but is not limited to a login and a password. The login and the password are used to sign in. I store the sign in information in a player object, and each player object is stored in an Array List called players. How do I prevent the player objects from being deleted when I compile the program. Am I doing this the right way? Should I be storing the players sign in information in a file? If so, I'm not sure how to do this. Please help. Thank you. My code:
In brief: objects last only as long as the program they're created by is running, unless you specifically do something to change that. Usually, that means having a way to store the objects in either a file or a database, and a way to load objects from the file or database.
So right now, your game is an application that people can run at the command line; it's not networked, and it's not set up to run indefinitely while various people log in and out. If you want it to stay like this -- i.e., someone runs the application, logs in, plays, logs out and the application quits -- then just saving the login data in a simple flat file would probably be fine.
