I'm trying to read /dev/input/js0 from Java but I keep getting

java.io.IOException: Invalid argument at java.io.FileInputStream.read0(Native Method) at java.io.FileInputStream.read(FileInputStream.java:207) at Test.main(Test.java:7)

My code is

import java.io.*; final class Test { public static final void main(String[] args) { try { FileInputStream in = new FileInputStream("/dev/input/js0"); System.out.println(in.read()); } catch(IOException e) { e.printStackTrace(); } } }

My end goal is to be able to read input from my controller but I can't even seem to read one byte. What am I doing wrong? My user does have read and write access to the file.

Wrapping the FileInputStream in a BufferedInputStream seems to fix the issue.
