Add Shutdown hook with JVM, which will be invoked even when application is killed by pressing CTRL + C
Create a separate class which extends java.lang.Thread class or implements java.lang.Runnable interface
public class AppShutDownHook extends Thread {
@Override
public void run() {
// TODO: Complete your shutdown activity here.
}
}
Register this thread with Java Runtime in your code where your application is getting initialised. Most probably inside main.
public static void main(String[] args) {
AppShutDownHook shutDownHook = new AppShutDownHook();
Runtime.getRuntime().addShutdownHook(shutDownHook);
