I'm a young software-developer and really at the begimming of Java. Nevertheless I've programmed a tool, which shows me via a table that contains an arraylist all the files in a specific directory. At the beginning the default directory C:\\ is set and after running the tool you'll see the table with all files in the directory.
I want to export the table to a CSV/XLS file, but I'm struggling weeks with the problem. Can you help me to find a right solution? I've seen some examples with the POI API, but I don't know how I could implement it in my programm ... Thank you in advance!
