Scala Iterator addString() method with a separator with example

This method is same as addString() method but here we can even include a separator between all the elements of an Iterator.

Method Definition : def addString(b: StringBuilder, sep: String): StringBuilder
Where, sep is the separator.

Return Type :It returns the elements of an iterator in the String Builder along with the separator stated.

Example #1:

// Scala program of addString()
// method along with separator

// Creating object
object GfG
{

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

        // Creating an Iterator
        val iter = Iterator(11, 12, 13, 14)

        // Applying addString method
        // with a separator
        val result = iter.addString(new StringBuilder(), "#")

        // Displays output
        println(result)

    }
}

Output:

11#12#13#14

Example #2:

// Scala program of addString()
// method along with separator

// Creating object
object GfG
{

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

        // Creating an Iterator
        val iter = Iterator(5, 6, 9)

        // Applying addString method
        // with a separator
        val result = iter.addString(new StringBuilder(), "*")

        // Displays output
        println(result)

    }
}

Output:

5*6*9
