Is this is a glitch? unable to complete task/quiz question help?

I'm 100% green to Java. So when you introduced a new variable and ask me to do something with it, I was really thrown for a loop. I have been working like 15 minutes on this one question.

Jordan Finnigan, glad you found help here! Remember to check the forum as you work through the projects, and you can also email us at help@teamtreehouse.com if you get stuck. Hope you get a lot out of the Android projects!

Hi @Mark,

Thanks for your feedback about this question! I went and reviewed the transcripts for my videos because I do talk about the "exclusive upper bound"......but not until the beginning of the next video. I must not have realized the timing when I wrote this code challenge.

I'll take a look at how best to fix this later this week, but for now, for you, you just need to plug in the correct parameter for the nextInt() method to get 10 numbers (0-9). "Exclusive upper bound" means that it's the upper bound of the range of numbers, but it's excluded from the actual range. So what would that be for the range 0 to 9?

What is the data type for intAsString? Remember that in Java, every variable needs to be declared as some sort of data type (String in this case). Check out my post two spots above yours in this thread for more help.

Also note that the toString method requires an int as a parameter. What int variable is already there in the Code Challenge?

Well counting the 0 all the way to 9 you would get 10 numbers correct or would that be 0 minus 9 getting -9?. Not exactly sure what you mean by range.

Ok i figured it out the answer was 10 i should have thought about how many numbers there where but I am stuck trying to understand the last question before the next video "Declare a String variable named intAsString. Convert the randomNumber integer to a String value and store it in the intAsString variable. Hint: Use the toString() method of the Integer class." I am unsure what the correct syntax would be as this was not in the previous video either.

Glad you figured it out! This next one actually was covered in the video. Check it out starting at the 4:37 mark.

All i know to do is write it out this way answer = Integer.toString(randomNumber);

and i have no clue where intAsString goes i have tried different things answer = intAsString(randomNumber); answer = Integer.toString(intAsString); answer = intAsString.toString(randomNumber); answer = Integer.intAsString(randomNumber); intAsString = Integer.toString(randomNumber); int = Integer.toString(randomNumber);

I wasn't sure if the question was asking for string answer; also but it appears it does, that was my problem. Thank you for explaining. :)

I'm a bit lost myself

intAsString = Integer.toString(intAsString);

Awesome that helped jog my memory. Thanks

Never mind, that post did help me when you broke down the structure..

I'm caught in the challenge of Java have seen the answer to Mark, but still going wrong I must have misunderstood the question or whatever, I understand "intAsString" goes in place of "answer" but soon realized it was not so accurate help me pass this stage, I'm from Brazil and language also impedes a bit for me because I'm not fluent in English and can be confusing something, help me please ...

Hi @Marcos,

Sorry you're having trouble! Can you post your code in here for us to take a look at? You can either add a comment in here or make a completely new post.

Just as a heads up, I also had a lot of trouble with the 4th task in this quiz. Had I not found this specific help article, I don't know if I would have been able to complete it.

Im still lost this is confusing.

Random randomGenerator = new Random();
int randomNumber = randomGenerator.nextInt(10);
intAsString = Integer.toString();

NM

This help me a ton thanks

That makes sense. Good thing I Googled this question today
