Hello Sir, Please also mention ways to break the Singleton Pattern with some practical examples.

Question. The last change seems to be creating a new instance for each call. The loop in main would create more than one instance? Static or not, you are newing up for each iteration of the loop. Correct?

[neerajagandla]

How does creating the instance in an inner class solve the problem during multithreading?

[venkatramana]

Could you please upload videos about Design principles like Open-Close, Dependency inversion.... etc ?

The flight tracking example you gave is understandable. But can you let me know why do we need to make the Satellite class singleton if we can make all its data static? Can you give an example where using singleton is the only option?

[ksaittis]

We do we need the helper class? Can't we just have an member variable in Satelite class like `private static final Satelite _instance = new Satelite();`
