First Question: What is the difference between %n and \n, don't they both make new lines?

Is there any difference between them?

According to the (Offical Oracle Java Documentation)[https://docs.oracle.com/javase/tutorial/java/data/numberformat.html]

The %n is a platform-independent newline character. [...] You should always use %n, rather than \n.

Note that this only works while using a "format" output,. if you were to use a plain old System.out.print(ln), it would act as a regular string.

System.out.println("using \n slash");
        System.out.println("using %n percent");

->

using 
 slash
using %n percent

\n is, specifically, a UNIX (Linux/macOS) newline, but is often converted by Windows into "\r\n\ for "return-feed-newline", and is effective when working with strings regularly.
