He knows how to make complex algorithms but doesn't know how to use copy-paste shortcuts

hello thenewboston,
I don't understand why in time 1:17 video
You demonstrate that we can use ++tuna to add 1 to tuna value
why now to just delete 5 and put 6 instead? -
Write in eclipse "sysout" press ctrl + space, thaks me later.
-
What is the purpose of having line #5(Scanner bucky = new Scanner(System.in);)?
I know this was used to get input from a user followed by a printing statement.
But what does this line(#5) do without the printing statement like in this video? -
Ive done java for nearly a year in my school and am really happy to have started from the playlist. I knew I would find little details like the tuna += 5, I knew about the tuna++ and tuna = tuna +5 but those are those little details that i know will make me a better java coder. Also I feel that mention of Sys.output(tuna++) saved me quite a bit. I never knew putting the ++ on end/start would have a difference. I hope to get to GUI in no time since that's what I'm going to have to learn soon and want to be ahead. It acts as a good revision tool too.

Could someone give me an example of when I would use a++ instead of ++a?
I'm having trouble thinking of an example.
-
can someone give me a brief definition on a assignment operator
-
What does exactly "tuna =+ 5;" do?
I don't know if it is the same as typing "tuna = 5;"
Could somebody use his/her skill to explain this problem? -
Can you do you do System.out.println(tuna+5); ?
-
import java.util.Scanner;
class apples{
public static void main (String args[]){
Scanner bucky = new Scanner(System.in);
int tuna = 5;
int bass = 18;
++tuna;
System.out.println(tuna);
}
} -
This helped me so much this helped me with my problem, I can finally go to bed.
-
You don't need the scanner if that's for input, why is it there? You're just printing something.
-
how does it go from 4.3 million to 850k?
-
Nice Video . I studied IT (networks). I decided to Java( more options for business ) I hope to overcome, never is too late.
-
man i really like to know who is Tuna?:D
-
brilliant video
-
I love how he keeps going "and I'll print this out in case you don't believe me" as if anyone's remotely skeptical.
-
Could I make it so the answer= num1 Action num2 and action being a value which can be specified by the scanner?
Like Action could equal / , % , + , – , or * -
I feel like an idiot – I understand what incrementing does (in that you can use it to + or take 1) but… WHY increment? For what practical purpose? I'm terrible at Maths which is why I don't get this.
Thanks so much for these videos – I've learned far more from these than my university classes, tbh. -
Assalam O alikum Bucky, I've been watching you for a long time and you're the best.
-
What are classes?
-
From 4,3 million in the first video to 787k in 9*6= 54 short minutes over 3 million gave up.
There is no easy way, I feel proud of myself and you should too who ever sticked around.
You have what it takes to become a programmer and make it. -
Why do we need to put Scanner here? 😮
-
These stuff are so easy if you have a basic knowledge of C++.From tutorial 1 to 30 was total easy for me.
-
this guy really likes tuna
