Want to know more about standard Java I/O concepts like standard input, standard output, and standard error? Read on!

The standard input or stdin device to give commands is the keyboard and the standard output or stdout device is your terminal screen. With redirection, you can change the standard input/output.

The Linux software includes a library of input-output function routines to speed code development. IP modules are additionally supported by C libraries for VxWorks and QNX realtime operating systems.

As you might expect, you can use the print and println macros for writing to standard output. Finally, you can read from standard input with the help of the io::stdin().read_line() function.

This is very different from <stdio.h> which contains functionality related to file access and operations, as well as input and output to and from standard out or in.
