Kotlin sets | Set in Kotlin | How to use set and mutable sets in Kotlin android

Kotlin sets tutorial shows how to work with sets in Kotlin. A set is a generic unordered collection of elements which allows no duplicates. Kotlin distinguishes between read-only and mutable sets. Read-only sets are created with setOf() and mutable set with mutableSetOf(). In this tutorial we are going to learn about mutable and read only sets in kotlin android.

Set interface Set out E : Collection E (Common source) (Native source) A generic unordered collection of elements that does not support duplicate elements. Methods in this interface support only read-only access to the set; read/write access is supported through the MutableSet interface.

Parameters E - the type of elements contained in the set. The set is covariant in its element type.
