How to get file name as a command line argument in Java

Question

I am making a simple program to read a file to get data from it for a project.I have hard coded the file name and directory in my Java code. But now I want to pass my file name as a command line argument in my program.Is there an easy way to do it?
Thanks!

Have a look at Oracle's documentation [here](https://docs.oracle.com/javase/tutorial/essential/environment/cmdLineArgs.html). — Darshan Mehta, Jul 01 '17 at 08:06

In your main method, there should be a parameter that is an array of strings. This paremeter holds the tokenized command line arguments passed when your program is executed.

If you run your app from command lines, then you can use argv[0] for full path or "%1" for file name only in your properties inspector.
