Java.lang.arrayindexoutofboundsexception: index 0 out of bounds for length 0

Java.lang.arrayindexoutofboundsexception: index 3 out of bounds for length 3

Since in java the first position of an array is 0, if an array has 
length 3 then the last element is in position 2. 

Ex: array = [elem0, elem1, elem2] then the last elem is index 2 
and the array has length 3
