About Question com.enthuware.ets.scjp.v6.2.504 :

[MC20147]

There's a small typo in the explanation of the correct answer:
"arr[0][1][2] => [0] = { { "a", "b" , "c"}, { "d", "e", null } }, [1] = { "d", "e", null } and [3] = null.
So it will print 'null'."

The [3] should actually be [2]

I spent a few minutes staring at the [3] trying to figure out how in the world that referenced the null

Thanks,

Mark

You are right, it should be [2]. This has now been fixed.

thank you for your feedback!
