It's not about the static import (which is fine), it's the unnecessary creation of an intermediate collection.
Oh lol, my initial desire was to answer the "Lecturer's question" and create a list first, so the code was initially different.
It initially created a list, assigned it to a variable and then worked on it, but when I shortened the code I didn't bother on (I might have felt lazy :/) to remove the creation of an intermediate collection.
Thanks for the advice though.
We’re a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
