Can anyone help me solve this Java problem?

Seeing as an plethora named a whose things are regarding type int may be declared, assign the actual value
-1
for the last element in a very.

This really is my answer but it surely is erroneous, where am i messing up

-1=aa.length – A SINGLE;

this will probably work
aa.length-1=-1;
because tasks are often done for the left side variable

Your job is counter clockwise.

The one thing on the actual left side of the = will be the destination; the one thing on the proper side will be the source.
