Mostly interviews asked this ...on how you can make single pattern thread safe !!! BTW very nice ...God bless you

nice

[@MrRana1478]

thanks Sir, Very well explained

[@dipikabhagat5252]

Thanks for the great explanation Sir !! . However, I have a question on lock mechanism . Suppose there are two threads trying to create singleton instance then how is the lock deciding which thread should go first?

[@CodewithRSV]

It is a very rare condition for 2 threads to try to acquire a lock at exactly same time but in that case there can be internal thread priorities which can be used. In any case, lock will prevent the threads to execute the code at same time.

[@dipikabhagat5252]

Thanks for the reply sir 👍

[@shagunagrawal3773]

Great knowledge i appreciate you 🤗

[@AmmaarNaveed-s5l]

Very comprehensively described !

[@RhymePlayKids]

Dose it require to make class as Sealed?

[@CodewithRSV]

It's not mandatory but if you don't make it sealed then someone can create a child class and create multiple objects of the child class. Sealed class will prevent the inheritance.

[@swapnilsonawane2525]

Is it the same way we create singleton class ?

[@CodewithRSV]

Yes, using singleton pattern and creating a Singleton class is same thing.
