Scala - Assessment - Declare an array

An array is one of the collections in Scala, which stores a fixed-size sequential collection of elements of the same type.

We will declare an array of strings, named strArray, having below elements in the same order.

Elements of the array:
John
Doe
Jane
Sach

In general, providing the datatype of the variable is optional. So, an array can be defined in either of the below ways:

var ar:Array[String] = Array(.....)

var ar = Array(.....)

But, the first statement specifies that the array will consist of strings only, so :Array[String] is required here.
