The length() method belongs to the concrete value members of the class AbstractIterator. It is defined in the class Iterator. It is also identical to the method size, it is also utilized to find the length of the stated collection.
Method Definition : final def length: Int
Return Type :It returns the length of the stated collection.
Example #1:
// Scala program of length() // method // Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Declaring an iterator
val iter = Iterator( 2 , 3 , 5 , 7 , 11 )
// Applying length method
val iter 1 = iter.length
// Displays output
println(iter 1 )
}
} |
Output:
5
Here, the stated iterator is non-empty so, the length of the given collection is returned.
Example #2:
// Scala program of length() // method // Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Declaring an iterator
val iter = Iterator()
// Applying length method
val iter 1 = iter.length
// Displays output
println(iter 1 )
}
} |
Output:
0
Here, the stated iterator is empty so, the length of the given collection is zero.
