Scala Iterator buffered() method with example

The buffered() method in Scala belongs to the concrete value members of the class iterator of Scala. It creates a buffered iterator from the iterator stated.

• Method Definition:

   def buffered: BufferedIterator[A]
  

• Return Type:
  It returns a buffered iterator which produces the alike values as the stated iterator.

Example :

// Scala program of buffered()
// method

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Declaring an iterator
        val iter = Iterator(3, 4, 5, 6, 7)

        // Applying buffered method
        val result = iter.buffered

        // Displays output
        println(result)

    }
}

Output:

non-empty iterator

Here, a buffered iterator of the stated iterator is returned after applying buffered method.
Example :

// Scala program of buffered()
// method

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Declaring an empty iterator
        val iter = Iterator()

        // Applying buffered method
        val result = iter.buffered

        // Displays output
        println(result)

    }
}

Output:

empty iterator

Here, the stated iterator is empty so, an empty buffered iterator is returned after applying buffered method.
