625 PointsChallenge Task 4 of 4
Task is: Initialize a new Random variable called randomGenerator using the Random() constructor. Hint: Don't forget to use the new keyword. But for some reason this code is not working on the website but works in Android Studio. There is also no skip button to get past this Task so i have been stuck on this question for 3 weeks without any luck.
String intAsString = "";
Random randomGenerator = new Random();
int randomNumber = randomGenerator.nextInt(10);
intAsString = randomGenerator + "";

5,121 Pointssimple syntax error, you have random\Generator as the variable where it should be randomNumber. quick fix and the code is good!

250 PointsSo you want to create a random number from 0-9, right? If you have imported import java.util.Random; then it should be fine. However, if you are trying to randomly generate a string you will run into a typecast issue. Let me which one you are trying to randomize, and I will walk you though the problem (without giving you the answer).

16,778 PointsString intAsString = ""; Random randomGenerator = new Random(); int randomNumber = randomGenerator.nextInt(3); intAsString = randomGenerator + ""; THIS works for me!!

250 PointsOk, I did the challenge and got it to work. I'll be on for a little while longer, so if you'd like some help let me know.

250 PointsTry not to "give" the answer away Jordan....:)
What he means is this...
Random randomGenerator; Random rand = new Random(); rand.nextInt(10);

625 PointsSo this is code from my Android Studio which works.
As you can see the only thing different is called "fact" not "intAsString" and random is (3) not (10)
This WORKS in android studio, its the STEP by STEP from the video before this question, i put this code into the "challenge" on the webpage and it doesn't work.
Thank you Jordan for explaining the error, as im not really trying to "learn" the way it needs to be for myself as it already WORKS on android studio and "if it aint broken dont fix it" seems to work well for me in the past so i was mainly looking for a way to get the website to accept this, which is weird as i get there are more then one way to do things with coding but the video teachs one way and the website seems to need another way to make it work.
that was the problem i was having but thanks to everyone for responding to my question so quickly, its taken me a few days to get back on here.

5,121 Pointswait until you progress my friend the code challenges get progressively more challenging. the way it works is the video's develop the idea and the challenge forces you to use the concept with new variables and methods. it's actually super helpful. so yeah you will need to pay close attention that you understand what is happening.

250 PointsRobert, I took time out of my busy schedule to help you solve this problem, and the answer I provided was correct given the challenge you provided. Unfortunately, I do not believe you understand the core concepts involved here. Programming is not about learning little "tricks". If you are serious about programming as an occupation, understand that you will be expected to take programming tests and explain fundamental concepts during interviews. Please do not take offense to this, as I am only trying to give you good advice.
