Scala Mutable SortedMap foreach() method with example

Last Updated : 4 May, 2020
The foreach() method is utilized to apply the given function to all the elements of the SortedMap.
Method Definition: def foreach(f: ((A, B)) => Unit): Unit Return Type: It returns all the elements of the SortedMap after applying the given function to each of them.
Example #1: Scala 
// Scala program of foreach()
// method
import scala.collection.SortedMap

// Creating object
object GfG
{ 

    // Main method
    def main(args:Array[String])
    {
    
        // Creating SortedMap
        val m1 = SortedMap(3 -> "geeks", 1 -> "for", 2 -> "cs", 6 -> "geeks")
        
        // Applying foreach method and 
        // displaying output 
        val result = m1.foreach(x => println("key=" + x._1 + ", value=" + x._2))
        
    }
}
Output: 
key=1, value=for
key=2, value=cs
key=3, value=geeks
key=6, value=geeks
Example #2: Scala 
// Scala program of foreach()
// method
import scala.collection.SortedMap

// Creating object
object GfG
{ 

    // Main method
    def main(args:Array[String])
    {
    
        // Creating SortedMap
        val m1 = SortedMap(3 -> "geeks", 1 -> "for", 2 -> "cs", 3 -> "geeks")
        
        // Applying foreach method and 
        // displaying output 
        val result = m1.foreach(x => println("key=" + x._1 + ", value=" + x._2))
        
    }
}
Output: 
key=1, value=for
key=2, value=cs
key=3, value=geeks
So, the identical elements are taken only once.
