At first glance, we see that this puzzle consists of a Java program. By running or inspecting this, we see that it simply outputs several lines of whitespace. Using the powers of google or our own obscure compsci knowledge, possibly with a nudge from the suggestive title, we realise that their exists a programming language that consists solely of Whitespace (and is aptly named as such)

Simply running a whitespace interpreter on the program produces no output. However, if we compare the program to the whitespace tutorial, we see that the first two lines each push a number to the stack (13, then 25). The third line swaps these around. The fourth line if a modulo operation, which computes 25%13 = 12 (the solution to the puzzle), and places the result onto the top of the stack. The final line indicates the end of the program.
