In this video i have explained what are the different ways we can achieve thread safety in Singleton Design Pattern.

There are basically three ways to achieve thread safety in singleton design pattern and that is:
1. Use mutex lock and unlock before and after checking if instance of singleton class is null or not, but there is a down side to this approach that is not good at performance side, we have to always apply mutex lock and unlock when getInstance is called.
2. Eager Instantiation (This is about instantiating singleton class by calling getInstance method early in main function so that before even threads start and race condition arise)
3. This approach is slight modification of 1st approach, this talks about keeping null check before mutex lock so that if once instance is available mutex lock would never be used and hence performance can be good.

Please feel free to comment and suggest if i can improve on this or any other topic, thanks.
