Add a new Virtual Machine Shutdown hook

NewVMShutdownHook.java

Runtime.getRuntime().addShutdownHook(new Thread(() -> {
  // Your code comes here...
}));

/* addShutdownHook() - A shutdown hook is simply an initialized but unstarted thread. When the virtual machine begins its 
shutdown sequence it will start all registered shutdown hooks in some unspecified order and let them run concurrently. When all the 
hooks have finished it will then run all uninvoked finalizers if finalization-on-exit has been enabled. Finally, the virtual machine 
will halt. Note that daemon threads will continue to run during the shutdown sequence, as will non-daemon threads if shutdown was 
initiated by invoking the exitmethod. */
