How to check if Two Sets are Equal in Kotlin - Step by Step Examples

How to check if Two Sets are Equal in Kotlin ?

To check if two sets are equal in Kotlin, you can use the == operator or the equals() method.

In this example,

We define two sets named set1 and set2.
We use the == operator between set1 and set2 to check if they are equal.
The == operator returns true if both sets have the same elements, in the same order, and false otherwise.

fun main() {
    val set1 = setOf(1, 2, 3, 4, 5)
    val set2 = setOf(1, 2, 3, 4, 5)
    println(set1 == set2)
}

true

In this example,

We define two sets named set1 and set2.
We call the equals() method on set1 and pass set2 as an argument.
The equals() method returns true if both sets have the same elements, in the same order, and false otherwise.

fun main() {
    val set1 = setOf(1, 2, 3, 4, 5)
    val set2 = setOf(1, 2, 3, 4, 5)
    println(set1.equals(set2))
}

true
