How to specify filepath in java?

I have created a java application for "Debian Linux." Now I want that that application reads a file placed in the directory where the jar file of that application is specified. So what to specify at the argument of the File Object?

File fileToBeReaded = new File(...);

What to specify as argument for the above statement to specify relative filepath representing the path where the jar file of the application has been placed?

Solution

  • If you know the name of the file, of course it's simply 

    new File("./myFileName")

    If you don't know the name, you can use the File object's list() method to get a list of files in the current directory, and then pick the one you want.
