Why are we using %n for newlines instead of \n in the JacksonsOldSchool.java for loop with arrays example?

Newline was accomplished by using \n previously. But in the JacksonsOldSchool.java for loop with arrays example, I encountered %n being used for newline. Please explain.

You should use the %n version as it is platform-independent. Craig mentioned at some point in some later video that he was not aware of it and he got to know it via the forum when someone commented on it, if I remember correctly.

Thanks for the answer @Pedro Cabral. Did a bit of search on google and found the below mentioned explanation: %n is portable between various platforms, the value emitted from %n will suits underlaying platform, where as value emitted by \n is same for all the platforms.

\n is the correct newline character for Unix-based systems, other systems may use different characters to represent the end of a line. Windows system use \r\n, and early MacOS systems used \r.
