This is a for statement i++, why every time I when can do print array mod10 line more than 9, is the number 10 line feed
Here "\ n" [Boolean value] and "\ n" Boolean value [] the second a space, effect, on the other hand, this effect: what is the logic and principle of
Is there who can teach me what is this principle, I'm new

Equivalent to print characters from the following characters, Boolean is true is to print the first character, are false, print the second character
Char [] s={' \ n ', '\ 0'}//a newline, the string end (equivalent to an empty string)

Not ah, there's a space that front, then true is 1, false is 0, array starting from 0, so true is a newline, equivalent to take out the second item from the array of strings
