Hi,

The following code is from Dan Chisholm's site



When I compiled and ran this program, the output was

nullException in thread "main" java.lang.ArrayIndexOutOfBoundsException: 2
at A14.main(A14.java:11)

I'm not able to understand why we are getting ArrayIndexOutOfBoundsException
Can someone please explain

Thanks,
Varsha

a3[2] points to a2.

a2[2] points to a1.

a1 only has one element.

so, a3[2][2] points to a1, which has one element, and then you try to access it's second element.
