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..
i think my declaration of BufferedWriter is wrong...
any suggestions are welcome.
