Hi,

When i'm calling a program, for example java Test <input.txt
i'd like to get the name of the file, in this example input.txt
How should i do this? I'm making a new DataInputStream(System.in), but I have no idea how I can get the name of the inputfile (because you also can't acces it in the args array of the mainmethod).
Thanks in advance.

Hello,

Why can't you access the filename as a parameter to main()?

Anyway, you could always pass in the name of the file as a "System Property" on the command line. Something like:


Good luck!

In that case, I think the only way is to access the parameter list in main().
Sorry!
