"Greetings, Amigo, my dear student. I'm glad to see you here at the library. I want to ask you something important: what do you think of Garbage Collectors?" 
"Oh… Professor, you know… I guess it could be my cup of tea if I were to stop learning how to program…"
"Ha! Amigo, sometimes you're really funny. However, this is a serious question and I'm talking about Java."
"Well, I have to admit I know nothing about the topic, sorry…"
"No worries, Amigo. That's okay for a CodeGym 6th grader. I have a useful article for you. It's called Object lifecycle. Please read it. You’ll find out how garbage collection works."
