Example #1:

Scala

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

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
        // Creating a SortedSet 
        val s1 = SortedSet(3, 7, 12, 9, 21) 
        
        // Applying foreach method 
        s1.foreach(x => println(x)) 
    
    } 
}

Output:

Example #2:

Scala

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

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
        // Creating a SortedSet 
        val s1 = SortedSet(1, 2, 3, 4, 5) 
        
        // Applying foreach method 
        s1.foreach(x => println(x + " times " + x + " = " + x*x)) 
    
    } 
}

1 times 1 = 1
2 times 2 = 4
3 times 3 = 9
4 times 4 = 16
