In Scala Stack class, the copyToArray() method is utilized in copying the elements of the stack to an Array.

Method Definition: def copyToArray[B >: A](xs: Array[B], start: Int, len: Int): Int

Parameters:
xs: It denotes the array where elements are copied.
start: It denotes the starting index for the copy to takes place. Its default value is 0.
len: It denotes the number of elements to copy. Its default value is the length of the set.

Return Type: It returns the elements of the stack to an array.

Example #1:




// Scala program of copyToArray() 
// method 
  
// Import Stack 
import scala.collection.mutable._
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating a stack 
        val s1 = Stack(1, 2, 3
          
        // Print the stack 
        println(s1
          
        // Creating an array 
        val arr: Array[Int] = Array(0, 0, 0, 0, 0)  
          
        // Applying copyToArray method 
        s1.copyToArray(arr) 
          
        // Displays output 
        println("Elements in the array: ")
          
        for(elem <- arr)  
            print(elem + " ")
    


Output:

Stack(1, 2, 3)
Elements in the array: 
1 2 3 0 0

Example #2:




// Scala program of copyToArray() 
// method 
  
// Import Stack 
import scala.collection.mutable._
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating a stack 
        val s1 = Stack(1, 2, 3
          
        // Print the stack 
        println(s1
          
        // Creating an array 
        val arr: Array[Int] = Array(0, 0, 0, 0, 0)  
          
        // Applying copyToArray method 
        s1.copyToArray(arr, 1, 2
          
        // Displays output 
        println("Elements in the array: ")
          
        for(elem <- arr)  
            print(elem + " ")
    


Output:

Stack(1, 2, 3)
Elements in the array: 
0 1 2 0 0
