Do you need a reflex for a beginner?

Question

Java

I began to study Java in 2 volumes. Went topics like reflection, proxy classes. Should we pay attention to them?

Answer 1

A beginner needs practice, as a rule, reflection can be dispensed with, but there are tasks in which it is used, usually it is associated with obfuscation, reverse engineering, information security, research, etc., but it is also used in "peaceful" solutions, for example, in MVC frameworks where you need to dynamically refer to a class and a method having a string with its name, but the study must come from practice, and not everything in a row that pleases some author of the book, that is, if you need an MVC framework, then study MVC -framework, and reflection in its context only when needed.
