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 s 1 = Stack( 1 , 2 , 3 )
// Print the stack
println(s 1 )
// Creating an array
val arr : Array[Int] = Array( 0 , 0 , 0 , 0 , 0 )
// Applying copyToArray method
s 1 .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 s 1 = Stack( 1 , 2 , 3 )
// Print the stack
println(s 1 )
// Creating an array
val arr : Array[Int] = Array( 0 , 0 , 0 , 0 , 0 )
// Applying copyToArray method
s 1 .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
