hai,
i am new to java.
i am developing an application, where the user enters a file or directory name and if it is a file ,then i have to write the filename to the .txt file.
i am using recusive method to test whther it is a file or directory, and if it is a file i want to write the name of the file to the .txt file, while running the below code i am getting the null pointer exception..

Which line causes the exception? Which object is null?

Line 77 will potentially set 'files' to null.

BufferedWriter will never print anything to the file until you call flush() on it.

you may want to handle cases in the modify method where your file doesn't match either of those if statements
