Scala Iterator filterNot() method with example

The filterNot() method belongs to the concrete value members of the class AbstractIterator. It is defined in the classes Iterator and IterableOnceOps. It selects all the elements of the stated iterator which do not satisfies the given predicate.

Method Definition : def filterNot(p: (A) => Boolean): Iterator[A]

Return Type : It returns a new iterator containing all the elements of the stated iterator that do not satisfies the given predicate p.

Example #1:

// Scala program of filterNot()
// method

// Creating object
object GfG
{

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

        // Creating an Iterator
        val iter = Iterator(3, 9, 5, 1, 13)

        // Applying filterNot method
        val x = iter.filterNot(x => {x % 3 != 0})

        // Applying next method
        val result = x.next()

        // Displays output
        println(result)

    }
}

Output:

3

Example #2:

// Scala program of filterNot()
// method

// Creating object
object GfG
{

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

        // Creating an Iterator
        val iter = Iterator(2, 4, 5, 1, 13)

        // Applying filterNot method
        val x = iter.filterNot(x => {x % 2 == 0})

        // Applying next method
        val result = x.next()

        // Displays output
        println(result)

    }
}

Output:

5
