> {{Long.parseLong()}} returns a primitive type but since method expect to return a {{Long}},
it needs to be wrapped. There are many more method like that. We might be creating a lot of
unnecessary objects here.
> I am not sure if JVM catches upto it and somehow optimizes it if these methods are called
enough times (or may be compiler does some modifications at compile time)
> Let me know if I am thinking of some premature optimization
