Thread: How and where do you save user settings?

OK, sooner or later everyone needs to save some user input data, like username/password for some server.
What are the techniques for saving the data?

Let's say I want to write a program similar to filezilla ftp client. The user creates a new ftp connection and wants to save host/port/username/password so that next time he does not have to type it manually.

How would I go about saving this data? A text file? a database entry somewhere? Do I have to specify the location (directory/file name) or does java automatically create some file for these?

Look at the Preferences class.
Or if you'd prefer using a file, look at the Properites class

Create a class that implements Serializable interface with the necessary field for your information (username, pasword, etc.), create an object of this class and save it on a file via ObjectOutputStream, check this link for the documention. ObjectOutputStream (Java 2 Platform SE v1.4.2)RL]

No, don't do that. Norm has already posted good and correct advice.
