I want to do something like-

class doSomeTask

 public static object do_method(object request)

 //Perform some operation on request

 response = doSomeOperation(request);

 //Want to do this task in background

 writeToDB(request, response);

 return response;

 

Process should return immediately after the response is generated while the write to database operation should be done in background.
daemon thread can do this task in background but it does not guarantee task completion.
So if you know any other methods then let me know.
Thanks.

public class Test 

 private static FutureTask<Void> future;

 public static Object do_method(Object request) 
 // Perform some operation on request
 Object response = doSomeOperation(request);

 // Want to do this task in background

 future = new FutureTask<>(new Callable<Void>() 
 @Override
 public Void call() throws Exception 
 
 writeToDB(request, response);
 return null;
 
 );

 // Start background thread and execute Callable (FutureTask is also a runnable)
 new Thread(future).start();

 return response;

 

 public static Object doSomeOperation(Object request) 
 return new Object();
 

 public static void writeToDB(Object request, Object response) throws Exception 
 throw new Exception(); // Simulation failure on SQL insert
 

 public static void main(String args) 
 Object request = new Object();

 Object response = do_method(request);
 // ... do some crazy stuff with response

 try 
 future.get(); // Wait for succesfull execution of background thread
 catch (Exception e) 
 // Catch ExecutionException if any uncaught Exception in the background thread is thrown
