Data-Structures 3/13 error?


My task should be to insert an ArrayList into the main method. Every time I try to run it, it tells me, I hadnt created an object, called "weeklyTemperatures", yet I did.
I tried restarting it, I tried copying the code and going back a few steps, going forward again and copypaste the code again... it just wont work...

Thanks for your help :slight_smile:

import 	java.util.ArrayList;

public class For {
	public static void main(String[] args) {
		ArrayList<Integer> weeklyTemperatures = new ArrayList <Integer>();



Hi but the class name should be

public class Temperatures { 
   #here put your main method


Hey, just to add onto what @wizmarco said..

It looks like having a space between

new ArrayList



may be causing the problem here. Try removing that space and with any luck it should pass.

Note: In any other environment that space wouldn't have been an issue, but because of the nature of Codecademy's environment sometimes these kind of pedantic issues will come up.


Thx so much for your help! I tried it but somehow it still didnt work. I solved it now: using another browser did the trick :wink:
