If you want to have your code os-unspecific you should use println for each word  System out println  I    System out println  am    System out println  a    System out println  boy      because Windows uses   r n  as newline and unixoid systems use just   n   println always uses the correct one

Example  System out printf  I  n am  n a  n boy      Output  I   am   a   boy   Explanation  It s better to use  n as an OS independent new-line character instead of  n and it s easier than using System lineSeparator    Why to use  n  because on each OS  new line refers to a different set of character s    Unix and modern Mac s       LF       n  Windows                     CR LF    r n  Older Macintosh Systems     CR       r    LF is the acronym of Line Feed and CR is the acronym of Carriage Return  The escape characters are written inside the parenthesis  So on each OS  new line stands for something specific to the system   n is OS agnostic  it is portable  It stands for  n on Unix systems or  r n on Windows systems and so on  Thus  Do not use  n  instead use  n

To make the code portable to any system  I would use    public static String newline   System getProperty  line separator      This is important because different OSs use different notations for newline  Windows uses   r n   Classic Mac uses   r   and Mac and Linux both use   n    Commentors - please correct me if I m wrong on this
