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
// 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
// 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
