> {{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
