TreeSet class, the copyToArray() method is utilized in copying the elements of the TreeSet 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 set to an array.Example #1:
// Scala program of copyToArray()
// method
// Import TreeSet
import scala.collection.immutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSet
val t1 = TreeSet(2, 1, 3, 4, 5)
// Print the TreeSet
println(t1)
// Creating an array
val arr = Array(0, 0, 0, 0, 0)
// Applying copyToArray() method
t1.copyToArray(arr)
// Displays output
println("Elements in the array: ")
for(elem <- arr)
print(elem + " ")
}
}
Output:
Example #2:
TreeSet(1, 2, 3, 4, 5) Elements in the array: 1 2 3 4 5
// Scala program of copyToArray()
// method
// Import TreeSet
import scala.collection.immutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSet
val t1 = TreeSet(2, 1, 3, 4, 5)
// Print the TreeSet
println(t1)
// Creating an array
val arr = Array(0, 0, 0, 0, 0)
// Applying copyToArray() method
t1.copyToArray(arr, 1, 2)
// Displays output
println("Elements in the array: ")
for(elem <- arr)
print(elem + " ")
}
}
Output:
TreeSet(1, 2, 3, 4, 5) Elements in the array: 0 1 2 0 0
