Answer 1

It is possible to add a shutdown hook to your Java program which is invoked if the JVM is shutdown for any reason (other than System.exit()) including O/S shutdown. Is that what you want?

Use: java.lang.Runtime.addShutdownHook(Thread):

Runtime.getRuntime().addShutdownHook(new Thread() {
    public void run() {
        // shutdown code here
        }
    });
