In this tutorial, you shall learn about Arrays in Kotlin programming language, the basics of arrays and array operations, with examples.
Kotlin Array is an ordered collection of similar type of values.
An array in Kotlin is of fixed size. Once an array is declared of specific size, the size cannot be changed. In other words, we cannot add elements to the array, nor delete elements from the array.
The value of an element can be modified/updated.
In Kotlin, arrays are implemented via Array class.
