Consider this method that prints a page number on the left or right side of a page:

if $($page $\%2==0)\{$ System.out.println$($page$)$; $\}$

else $\{$ System.out.println$("........................"+$ page$)$; $\}$

Introduce a method isEven with the return type boolean to make the condition in the if statement easier to understand.
