Your singleton implementation is wrong
if(rideService == null) {
return new RideService();
}
change it to
if(rideService == null) {
riderService= new RideService();
return riderService;
}
same in CabBookingService and UserService.
Otherwise it is not singleton as you are creating a different instance always.
I think the scope of multithreading is not here.so it is fine to keep it not synchronized.
Thread unsafe implementation of Singleton in UserDAO
Hi.
You have thread unsafe implementation of UserDAO's singleton.
If you have multiple threads concurrently requesting the object you will end up creating two copies.
