How to run IntelliJ IDEA with argument and redirect symbol <?

This is a question which is different from

How do you input commandline argument in IntelliJ IDEA?

The point of this question is, run with the redirct symbol

<

So in command line I can do this

java -cp /classpath MyClass < data.txt

which works good.

But I followed official help document of Intellij and tried to put redirect symbol < in argument.

enter image description here

Intellij threw an

Exception in thread "main" java.lang.IllegalArgumentException.

And I didn't find any illustration about using redirect symbol < with arguments in official help document.

IntelliJ does not support redirect symbol for now. It's really painful~!

As a compromise, you could try:

FileInputStream fis = new FileInputStream("E:\\GDUT\\Dropbox\\Alg4\\test_data\\eval.txt");
System.setIn(fis);

For the Program Arguments field, put in a path to the file, instead of the redirect symbol.

So if your IntelliJ project main directory is 

/home/glenn/Proj_java/Algorithms/Chapter1/BinarySearch

and your file data.txt is in that directory, just put in this:

data.txt

If you had a subdirectory under that named "mystuff" which contained your file, in Program Arguments use the relative path to the file:

mystuff/data.txt
