In Scala immutable 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 t 1 = TreeSet( 2 , 1 , 3 , 4 , 5 )
// Print the TreeSet
println(t 1 )
// Creating an array
val arr = Array( 0 , 0 , 0 , 0 , 0 )
// Applying copyToArray() method
t 1 .copyToArray(arr)
// Displays output
println( "Elements in the array: " )
for (elem < - arr)
print(elem + " " )
}
} |
Output:
TreeSet(1, 2, 3, 4, 5) Elements in the array: 1 2 3 4 5
Example #2:
// 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 t 1 = TreeSet( 2 , 1 , 3 , 4 , 5 )
// Print the TreeSet
println(t 1 )
// Creating an array
val arr = Array( 0 , 0 , 0 , 0 , 0 )
// Applying copyToArray() method
t 1 .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
