Scala Iterator toString() method with example

The toString() method belongs to the concrete value member of the class Abstract Iterator. It is utilized to convert the stated iterator to a string.

Method Definition: def toString(): String

Return Type: It returns a string from the stated iterator.

Example #1:

// Scala program of toString()
// method

// Creating object
object GfG
{

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

        // Creating a Iterator
        val iter = Iterator(2, 1, 10)

        // Applying toString method
        val result = iter.toString

        // Displays output
        println(result)

    }
}

Output:

non-empty iterator

Example #2:

// Scala program of toString()
// method

// Creating object
object GfG
{

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

        // Creating an empty Iterator
        val iter = Iterator()

        // Applying toString method
        val result = iter.toString

        // Displays output
        println(result)

    }
}

Output:

empty iterator

In above example, iterator is empty so produced result is also empty iterator.
