Assuming that you want to open the files, remember that File in Java is an object that stores path and name information. Once you have created the file objects, you can use them to construct a FileInputStream or one of its children.

You cannot pass files as command line arguments, you have to pass file names as command line arguments and open that file in main function

You need to pass in the url of the files via command line and then create new files from the urls. 

public static void main(String[] args) {
    File file1 = new File(args[0]);
    File file2 = new File(args[1]);
