Hooray for Bill Pugh, and hooray for you for explaining this better than a couple of other places I looked at where I was still confused. I totally get it now!

Nice video but I am not clear about how bill Pugh singleton is thread-safe?

[ashishupadhyay]

You did not explain, why it is thread safe?

[jvsnyc]

A lot of people who are careful about their terminology avoid ever saying "static inner class". They will call what we use here for SingletonHolder as "static nested class". "Inner Class" as a term they will use only to mean a member inner class, defined without static keyword, local or anonymous inner class. While those are three different things, they all have in common that they are associated with an instance of the outer class. I did not always make this distinction, but other people I learn from or discuss things with (and some authors I read) are very careful about that. So "static nested class" -- not owned by or associated with an instance of the outer class, can exist without any instance of the Outer class even existing, and several types of Inner Class, which can have differences, but in each case are indeed associated with an instance of the Outer class and maintain a reference to it.

Please tell why this approach is thread safe????
