    Yo! Can you explain how to compare the current item with previous or next, or some other without getting "outofbound" exception?

    I see way too many people saying that you should slow down, but I strongly disagree. The beautiful thing about these videos is how perfectly compressed the information is. Pause if you need a second.

    I know you want to give us a lot of information, but this is waaaay to fast.

    Towards the end you introduce the Arrays.sort() function for a one dimensional array, though i can't figure out how to use it for a 2 dimensional array, I receive a Class Cast Exception.

    I know this tutorial is old but can someone explain to me why when he printed
    an array with random numbers, they were in order instead of random places?

    The typed-code with comments combined with the video is a better resource than a semester at a college since we can type as we go at our own pace. This is insanely great at an intermediate level, and I am enjoying every moment of it.
    Coding is not for everyone and even though you make insanely easy, people still complaining about it. But I just want to say Thanks Very Much for making these series, and also I am a big fan of your work.

    I actually have not made it through all of your videos yet. Do you have a video where you use the API on something that you DON'T KNOW? I would like to see your thought process on that please.

    Why is coulum a string while it's holding an int and what are those ':' signs used for plz answer.

    in the first (numberarray) array, Why did you make two for loops one for (i)and one for (j) since you are making only one-dimensional array???

    speaking very fast

    Hey man really loved your videos, its not boring and at the same time it makes the viewers think about the code. I have one question if we store 1-10 numbers in numbersArray why cant we just use System.out.print(numbersArray)? i tried it but I'm getting a weird output like I@6bc168e5

    Video 10 and 8 are the same title just worded differently

    Question about the method: .length. For example multiArray.length; length is a method and methods always end with ( ). Why isn't this the case for length. ?

    Covred a lot in short time ! Kindly slow down a bit .

    the binary search gave me a negative number even tho the number was in the array

    To anyone getting confused, I would recommend don't get hung up here. If you don't understand it, try the best you can to replicate it and at least understand kind of what is gong on, and continue forward. Sometimes things will make sense later or when you understand other concepts. Obviously come back.
