Scala SortedMap copyToArray() method with example

  • Last Updated : 03 Nov, 2019

The copyToArray() method is utilized in copying pair of keys of the SortedMap to an Array.

Method Definition: def copyToArray(xs: Array[(A, B)]): Unit

Return Type: It returns the keys of the SortedMap to an array.

Example #1:




// Scala program of copyToArray()
// method
import scala.collection.immutable.SortedMap
  
// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a SortedMap
        val m1 = SortedMap("geeks" -> 5, "for" -> 3, "cs" -> 2)
          
        // Creating Array 
        val x: Array[Any] = Array(0, 0, 0, 0, 0
          
        // using 'copyToArray' method 
        m1.copyToArray(x) 
          
        // Displays keys copied in 
        // the Array 
        for(m2 <-x) 
        println(m2
    }
}
Output:



(cs, 2)
(for, 3)
(geeks, 5)
0
0

So, here the keys are copied to the array.
Example #2:




// Scala program of copyToArray()
// method
import scala.collection.immutable.SortedMap
  
// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a SortedMap
        val m1 = SortedMap("geeks" -> 5, "for" -> 3, "geeks" -> 5)
          
        // Creating Array 
        val x: Array[Any] = Array(0, 0, 0, 0, 0
          
        // using 'copyToArray' method 
        m1.copyToArray(x) 
          
        // Displays keys copied in 
        // the Array 
        for(m2 <-x) 
        println(m2
    }
}
Output:
(for, 3)
(geeks, 5)
0
0
0

Here, the identical keys are removed.
