Kotlin Array declaration access changeAn array is a homogeneous data structure, that stores a sequence of consecutively numbered values--allocated in contiguous memory. Each object of the array can be accessed by using its number (i.e., index).
In Kotlin to create an array we use the built in function
arrayOf()and we place values inside parentheses with comma separated format.

Access the Elements of an ArrayTo access an element in an Array we will need to use the index of that element for example:
array_namein this example we access element at index 1 for array arra_name, we use braces to surround the index.
Change an Array Element in Kotlinto change an array element we just need to use the existing index and set a new value. See below example :

sizeto get the length and number of elements in an array. See example below:
Kotlin Check if an Element Existsin Kotlin the operator
inis used to identify if an element exist in array and it will return true if exist and false if not. See example below:
