Where should I close the FileInputStream?
Hi! The last condition does not validate even if I close the FileInputStream in line 52. I also tried closing it in the while loop of the main method. I wrote "if (rd.fis != null) { rd.fis.close(); }" after I added data to my map, but that didn't work either. Any suggestions for solving this task?

Okay so I've understood the program enough to write something, but I don't understand why....?
Uncomment lines 23, 60 and 61 to test the program and see. Maybe you could find where I got it wrong. Recommendation from the mentor was: Be sure that the lines list has the REMOVED label with the required lines in the correct places.
