There is a stackoverflow answer : "You can use LOG such as :
Log.e(String, String) (error)
Log.w(String, String) (warning)
Log.i(String, String) (information)
Log.d(String, String) (debug)
Log.v(String, String) (verbose)"

i really appreciate you man, i am taking java android course in my university . your tutorial is just great

what is logcat? well, on *nix based systems, of which android devices are a descendant, 'cat' is the command for concatenating files on the console. if users on a box wanted to view any kind of file, like an application log for example, they could type 'cat fpn' where fpn stands for full path name, and the text would appear on the screen. "cat the log for me" was a common thing you'd hear. of course those were the days where looking at logs was so common it didn't take an act of congress just to do basic OS commands like it does these days.

though @christatic really did help with their comment and resolved the first question I had,
and though I don't have an error showing up anymore, it still won't present anything in my log for some reason after I've seemingly gotten it all right and did everything exactly like u show here. I guess I'll read into it more when I actually get to needing it. The rest is working alright for me so far and I really like the videos generally. Thank you, keep at it♥. If you get a chance to let me know what might have gone wrong here, It'd be great and I'd appreciate it.

What is the diffrence of it with writing System.out.println() to see that is it working or not ?

not working on mine. Android is overly complex and unpredictable
