Scala Mutable SortedSet foreach() method

In Scala mutable collections, SortedSet foreach() method is utilized to apply the given function to all the elements of the SortedSet.

Method Definition: def foreach(f: (A) => Unit): Unit

Return Type: It returns all the elements of the SortedSet after applying the given function to each of them.

Example #1:

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

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {
        // Creating a SortedSet
        val s1 = SortedSet(13, 22, 19, 21)

        // Applying foreach method
        s1.foreach(x => println(x))

    }
}

Output:

13
19
21
22

Example #2:

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

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {
        // Creating a SortedSet
        val s1 = SortedSet(5, 7, 8, 3, 2)

        // Applying foreach method
        s1.foreach(x => println(x + " times " + x + " = " + x*x))

    }
}

Output:

2 times 2 = 4
3 times 3 = 9
5 times 5 = 25
7 times 7 = 49
8 times 8 = 64
