events - Calling function when program exits in java -

-

i save programs settings every time user exits program. need way call function when user quits program. how do that?

i using java 1.5.

you can add shutdown hook application doing following:

runtime.getruntime().addshutdownhook(new thread(new runnable() {     public void run() {         // want     } }));

this equivalent having try {} {} block around entire program, , encompasses what's in block.

please note caveats though!
