Kotlin Array FAQs
No, in Kotlin, arrays are homogenous, meaning they can only hold elements of the same data type. If you need to store mixed data types, consider using lists or other collection types.
No, the size of an array in Kotlin is fixed upon creation. If you need a dynamically sized collection, consider using other data structures like lists (e.g., List or MutableList).
Kotlin provides a variety of functions for array manipulation, including filter, map, reduce, sum, average, and many more. These functions allow you to perform operations on array elements easily.
arrayOf() creates an array of nullable objects, whereas intArrayOf() creates an array of non-nullable integers. Similarly, there are other XXXArrayOf() functions for different data types.
