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?

resultMap.put(fileName,rd.frequentFinder());
