Scala mutable SortedSet equals() method

In Scala mutable collection, equals() method is utilized to check whether the two SortedSets have the same elements or not.

Method Definition: def equals(that: Any): Boolean

Return Type: It returns true if the elements of both the SortedSets are same else it returns false.

Example #1:

// Scala program of equals()
// method
import scala.collection.mutable.SortedSet

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating SortedSets
        val s1 = SortedSet("geeks", "for", "cs")
        val s2 = SortedSet("cs", "for", "geeks")

        // Applying equals method
        val result = s1.equals(s2)

        // Displays output
        println(result)

    }
}

Output:

true

Example #2:

// Scala program of equals()
// method
import scala.collection.mutable.SortedSet

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating SortedSets
        val s1 = SortedSet(11, 10, 2019)
        val s2 = SortedSet(9, 10, 2018)

        // Applying equals method
        val result = s1.equals(s2)

        // Displays output
        println(result)

    }
}

Output:

false
