ok for some reason I keep getting this error. I know that it normally happens when u forget to put in a curly brace and the compiler thinks your trying to define a function within a function but I cant seem to fix the error sooo hopefully someone here would be able to help me.

Also for those who are wondering, the code just creates a 3D cube (with out using java3d) and your able to change the camera view with the mouse but im trying to make it so that you could move it around with the keyboard. Oh and the error is happening around line 136
