Apr 22, 2012 - its cuz he used the syntax's of int, which stands for integer, so it will always come out as a whole number

Apr 23, 2012 - Two this that could've made this code more efficient. Firstly, instead of dividing by 10, divide by the counter, it's more reliable.Additionally on like 13 you could've had "total += grade;"

Apr 23, 2012 - Shortcut: If you are using Eclipse and you press CTRL + Shift + O, then it will automatically figure out what imports you need such as "import java.util.Scanner" and insert that for you.

IlyasWidaad Says:

Apr 29, 2012 - what does the nextInt() method do? Why couldn't you just say grade = input? Your goal is to just take the input from the command line and store that value in the variable grade, correct? then wouldn't grade=input work? Please clarify, thanks. :-)

djleisheng Says:

Apr 29, 2012 - IlyasWidaad: if you do grade = input you are assigning the input object instance of Scanner to an integer. You have to use the method nextInt() to actually get what the person entered, otherwise you are just trying to get the entire object

Apr 29, 2012 - If counter is less than 10 wouldn't it let you only input 9 numbers since it can only be less than ten. not equal to ten

khdalamoudi Says:

Apr 29, 2012 - Remember that the counter starts at 0, not 1, so you have 0, 1, 2 ... 9, and those are 10 :)

punkeltje Says:

May 2, 2012 - 7th and 8th line can be put together :Dint grade, average;and total = total + grade can betotal += gradekeeping it tidy xD

MrMetemer Says:

May 4, 2012 - my one asks how many grades you have! fuck yeah!

eldest808 Says:

May 4, 2012 - you rock dude thanks for these videos

drfrendor Says:

May 10, 2012 - You can also combine total and counter in that:int grade, average, total = 0, counter = 0;so you can get them all in one line. (=

May 13, 2012 - what does this mean? Error occurred during initialization of VMCould not reserve enough space for object heap

IamTraversy Says:

May 15, 2012 - Using this tutorial and knowledge from the previous video, as well as a little trial and error, I made it ask how many numbers you wanted to average, and then it would ask for that amount of numbers.Then it would add up the numbers like it is supposed to, and divide it by the number for the average you entered. These tuts are great, I thank you for making them!!

punk6743 Says:

May 21, 2012 - add another variable and a print line asking how many numbers are being inputted, then use (var) = (scanner).nextInt();. use this variable in place of the 10 for the while parameter aswell as average = total/(var) in place of total/10. doing this will allow the user to choose the amount of numbers being inputted.

RatedProfessional Says:

May 21, 2012 - I literally just did that, and came to post for users to try lol. Make sure in the while loop you change < 10 to < (var) so the amount of trials the user inputted will be allowed to be inputted.

punk6743 Says:

May 22, 2012 - haha awesome!! great minds think alike! lol

superstarben37 Says:

May 25, 2012 - Bucky, you do realise that instead of doing 'total = total + grade', you can compact it and do 'total+=grade'?
