Difference between ?System.out.println? and
?System.err.println??
The java.lang.System provides 3 static fields System.out,
System.err and System.in which represent the standard output
stream, standard error stream and standard input stream
Standard Output stream connects the program to the system
console screen and is commonly used to display informative
messages to the user.
Standard Error stream by default connects the program system
console screen and is commonly used to display error
messages to the user.
The Standard Input stream connects the program to the system
keyboard device and provides capability to the program to
read from keyboard input.
Java provides facilities by which these streams can be
redirected to other sources or destinations and change the
way the program behaves.
For example, the standard error stream can be redirected to
a output stream that writes to a log file for error analysis.

Answer / subrahmnyareddy
We can redirect System.out to another file but we cannot
redirect System.err stream.
ex:
public class TestSystOutAndErr
{
public static void main(String[] args)
{
System.out.println("system.out.message");
System.out.println("system.err.message");
}
}
compile:
>javac TestSystOutAndErr.java
execute:(first time)
>java TestSystOutAndErr
OutPut:
system.out.message
system.err.message
execute:(second time)
>java TestSystOutAndErr > samp.txt
output:
system.err.message
(In the above execution "system.out.message" redirected in
to samp.txt file but "system.err.message" not redirected
into samp.txt file)

Answer / narendrakumar
System.out.println(""); are used for displaying the data on
the console monitor and also send the data to the files...
But In System.err.println(""); mainly used for displaying
the err msg on the console monitor(stderr(standard
error))But we
cannot send the data to the file...only console monitor
