2 days ago a was a 22 years old university student that was studying computer engineering and tried to cheat my Java exams. After im done with these tutorials my teacher is going to cheat so she can give me less points in the upcoming exams.

@rymantas59 I don't believe he is actually in a university. After all he called his Professor a teacher -_-

@rymantas59 They probably go to ITT Tech or the we don't care give us money school if you prefer.

@MusicRevelance You are 22 year old and you dont know how to play with arrays? What a fukcing university you go to?

@EntropyVX Oh, okay. I understand, now. I should've realized that before... Thanks.

@Lennybird91 The + is simply adding the variable to the println statement.

System.out.println("some stuff:" + sum + "some more stuff " + sum + "yet more stuff");

[Insomniac10102]

@Lennybird91 It does seem a bit odd to have to use a '+' before sum, but the fact remains that no matter what you pack on other than the initial "The sum of ____ is", will need one. So when you think about it, you still are adding -in a sense- to the rest of the println. Hope that helps... Somehow.

@BigRunescapeBrain Counter-Grammar-Nazi-Activated­: It's "it's," not "its" when not discussing possession. ;-)

As for what you pointed out, we fall into vague territory. Considering words such as "team" or "group" when in unison are both still singular, one might question whether the "sum" is behaving as singular. This of course depends, as I've neglected to remember the importance prepositional phrases ("of these numbers") when noting the plurality of the verb. Doh.

[Lennybird91]

I'm having difficulty understanding why one can't simply output ..."The sum of these numbers is " sum); Why all of the sudden, after appending the sum+=bucky[counter];, do you have to use +sum?

@RiaAndPreetiAntics You could use nested for loops, one dimension inside of the other.
