Kotlin Set indexing Example

Each element of a set has an index. Kotlin set indexes to start from zero. The last element has len-1 index.

Kotlin Set indexing Example

The following example presents the Kotlin Set indexing operations.
package net.sourcecodeexamples.kotlin fun main() { val fruits = setOf("banana", "mango", "apple", "orange", "banana") val w1 = fruits.elementAt(0); println(w1) val i1 = fruits.indexOf("banana") println("The first index of banana is $i1") val i2 = fruits.lastIndexOf("banana") println("The last index of banana is $i2") }
Output:
banana The first index of banana is 0 The last index of banana is 0
