Question

We have a standalone java swing app, in which the user can print something that he drew, on a printer by giving its IP.

Now the requirement is that the app needs to remember the ip that was given the last time by this user.

What I could think of till now is (a brute one though) – keep a log file kind of storage on the client machine, and that everytime the app comes up it reads the last submitted one.

Any suggestions would be helpful.

Thanks in advance.

Here’s a tutorial on using the Java Preferences API to achieve what you want.
From the article:

The Java Preferences API provides a
systematic way to handle user and
system preference and configuration
data, e.g. to save user settings,
remember the last value of a field
etc.

I would use this approach over writing any data out explicitly to a file because its platform agnostic.
