assume you have a class test1 written with System.err and
you have a class test2 written with Sytem.out
when you try :java test1>>log.txt, you will see the output displayed on the console
when you try :java test2>>log.txt, you will never get output ont the console and you can find those output in the log.txt
that's the distinction between them.hope it helps.
