Scala : Reference to array element out of bounds

In the application, one of the execution paths contains a call of an array element out of bounds, which can lead to incorrect application behavior or crash.

An array is a data structure, which stores a fixed-size collection of elements of the same type which is stored contiguously in memory. An array element is accessed by an index, the value of which must be in the range from 0 to sizeArray - 1. When accessing an element by an index that is outside this interval, ArrayIndexOutOfBoundsException is thrown during execution.
