Array Out of Bounds Exception
ramesh
Iam a newbie to java and debugging a program(s). Iam unable to
figure out the Array out of bounds exception iam facing with. The
exceptions iam getting is as below:
Can you plz. tell me where to start with. From the stack trace doesit
mean that the error has occured in JSDOGeometry.java's reOrientCurves
method? If so, even if I print some thing in this method ( even as the
first statement in the method),its not getting printed. please guide
me.
Thanks in advance,
ramesh

Yes. You are apparently traversing
an array in it apparently.

What are you printing?

You wrote this class, right?
The error is telling you to look at line 223
of the source. That is where the AIOOB exception
is occuring.
I cannot see line 223 of your code from here,
but from the sounds of the length of it..
No, do not post it to the group as is. ;-)

Even worse - it is at line 1223 (linebreak in the number). ;)

Hello Ramesh
ArrayIndexOutOfBoundsExceptions occur when you tell Java to access an
array-element at a place that is outside the actual array.
For instance if I do this:
int[] int_array = int[8];
for( int i = 0; i <= int_array.length; i++)
int_array[i] = i;
-then it will generate an ArrayIndex...Exception when i reaches 8, because
the array only has places 0,...,7 - equal to (int_array.length - 1).
So check that you are not using a loop-condition that looks like
i <= array.length
-anywhere near line 1223 in your code.

Missed it by _that_ much. ;-)
