n is an escape character for strings that is replaced with the new line object  Writing  n in a string that prints out will print out a new line instead of the  n  Java Escape Characters

In the specific case of the code example from the original question  the   System out print   n      is there to move to a new line between incrementing i   So the first print statement prints all of the elements of Grid 0  j    When the innermost for loop has completed  the   n  gets printed and then all of the elements of Grid 1  j  are printed on the next line  and this is repeated until you have a 10x10 grid of the elements of the 2-dimensional array  Grid

as per http   java sun com    ex Pattern html   The backslash character       serves to introduce escaped constructs  as defined in the table above  as well as to quote characters that otherwise would be interpreted as unescaped constructs  Thus the expression    matches a single backslash and   matches a left brace     Other examples of usage         The backslash character lt br gt   t The tab character    u0009   lt br gt   n The newline  line feed  character    u000A   lt br gt   r The carriage-return character    u000D   lt br gt   f The form-feed character    u000C   lt br gt   a The alert  bell  character    u0007   lt br gt   e The escape character    u001B   lt br gt   cx The control character corresponding to x  lt br gt
