Kotlin List contains() Example

This example shows how to use contains() method to check if a list contains the specified elements.

Kotlin List contains() Example

package net.sourcecodeexamples.kotlin fun main() { val nums = listOf(1, 2, 3, 7, 6, 5, 4) val r = nums.contains(4) if (r) { println("The list contains 4") } else { println("The list does not contain 4") } val r2 = nums.containsAll(listOf(1, 6)) if (r2) { println("The list contains 1 and 6") } else { println("The list does not contain 1 and 6") } }
Output:
The list contains 4 The list contains 1 and 6
