Thanks for the reply @sam_stafford
I logged it as a known bug @cshuptrine and received a reply, copied below, from Andrew on the support team. I’m going to give it a try later today and tomorrow to see if it implemented and will report back. My students were working on the 1-day version of the Personal Narrative project and that is what I logged the bug about - so not sure if it will be implemented in the regular project - Lesson 10 - or any other lesson. But he notes it will not work on any sandbox level.
We appreciate you reporting this!
Our team has now added the FileReader class to Lesson 14. You should see this in the next few days when our system updates.
These reports help us make our site and offerings better for everyone, so thanks again for taking the time to send us this information!
Please be aware that the FileReader class will not be present on any sandbox level. Here are 2 projects that you can copy that class from:
FileReader for 1D/2D Arrays
FileReader for ArrayLists
These both serve different types of data. You will need to click “New File” and rename the file FileReader.java , Then you can copy/paste the class code from these links into your Java project. This will not work on levels where FileReader is already present as a support file (can’t have two files with the same name). However, it will work on all project / sandbox levels.
