Java read file by command line, <(less than) symbol

Question

I am trying to read the filename by the command line,

This is command that our professor wants us to type:

java MultiBinaryClient xxxxxx.edu 6001 <         


        

Answer 1

Let's see what each fragment means. This is how we execute a Java class containing a main method:

java MultiBinaryClient

The only command-line arguments that are being passed to your program are these ones:

xxxxxx.edu 6001

And this snippet is not part of the expected arguments to the Java program:

< files.txt

It's just Unix shell syntax to specify that the contents of files.txt must be read into your program via the standard input.
