title: When is it appropriate to use blank final variables?
body: <p>I was looking at another <a href="https://stackoverflow.com/questions/11345061/why-must-a-final-variable-be-initialized-before-constructor-completes">question</a> about final variables and noticed that you can declare final variables without initializing them (a <a href="https://en.wikipedia.org/wiki/Final_%28Java%29#Blank_final" rel="nofollow noreferrer">blank final</a> variable). Is there a reason it is desirable to do this, and when is it advantageous?</p>
