Java using a '<' symbol to read file contents from command line [closed]

I am trying to solve the josephus problem, but with a bit of a twist when it comes to syntax. The user needs to be able to enter data in the following format:

java Josephus 3 java.util.ArrayList < test.txt

the 3 is used as the number of people skipped in the problem itself, but the rest is where it becomes complicated, the user is to enter the name of a class that extends a list, as well as use the '<' symbol to enter the file to be used, only problem is I have no earthly idea how to access the contents of this file and reflect the classname to create an object

edit: for clarification, the test.txt file contains names, and will be taken into the list as strings.

I am currently using the following line for reflection:

List list = (List) Class.forName(args[1]).getDeclaredConstructor().newInstance();

and the following lines for reading from the file:

      Scanner scan =  new Scanner(System.in);

      while (scan.hasNext()) {
         list.add(scan.next());
      }
