The toSeq() method belongs to the concrete value member of the class Abstract Iterator. It is equivalent to the Seq method but this method is more faster.
Method Definition: val result = iter.toSeq
Return Type: It returns the stated collection as a sequence.
Example #1:
// Scala program of toSeq() // method // Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a Iterator
val iter = Iterator( 2 , 5 , 7 , 8 , 9 )
// Applying toSeq method
val result = iter.toSeq
// Displays output
println(result)
}
} |
Output:
Stream(2, ?)
So, here a sequence is obtained.
Example #2:
// Scala program of toSeq() // method // Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating an empty Iterator
val iter = Iterator()
// Applying toSeq method
val result = iter.toSeq
// Displays output
println(result)
}
} |
Output:
Stream()
So, here an empty iterator is obtained as the stated iterator is empty.
