what is +=??
increment the value on the right by the value on the left( so i += j means increment j by i). :)
This website seems pretty snobby condsidering the questions asked, how they are explained, and how people talk to each other in the discussions. I did a code camp and know some fairly tricky things and most of these questions seem designed for those who either have math degrees or those who already know a lot about Java and want to keep their skills sharp. "Easy"? Sure... How would a Java beginner even know there is a Math.pow method to import?
Anyway, check out codingbat.com for more straightforward questions that actually range from beginners to advanced. Also look into codecademy.com. Really great resources for FREE.
dang this helps a lot. Thank you so much
