Scala Map addString() method with a start, a separator and an end with example

This method is same as addString() method but here a start, a separator and an end is also included.

Method Definition: def addString(sb: mutable.StringBuilder, start: String, sep: String, end: String): mutable.StringBuilder

Where, sep is the separator stated.

Return Type: It returns the elements of the map in the String Builder and a start, a separator and an end is also included here.

Example #1:

// Scala program of addString() method
// with a start, a separator and an
// end

// Creating object
object GfG
{

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

        // Creating map
        val m1 = Map("geeks" -> 5, "for" -> 3, "cs" -> 3)

        // Applying addString method
        val result = m1.addString(new StringBuilder(), ">>>", "|", "--")

        // Displays output
        println(result)
    }
}

Output:

>>>geeks -> 5|for -> 3|cs -> 3--

Example #2:

// Scala program of addString() method
// with a start, a separator and an
// end

// Creating object
object GfG
{

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

        // Creating map
        val m1 = Map("geeks" -> 5, "for" -> 3, "for" -> 3)

        // Applying addString method
        val result = m1.addString(new StringBuilder(), ">>>", "|", "--")

        // Displays output
        println(result)
    }
}

Output:

>>>geeks -> 5|for -> 3--

So, here the identical keys are removed.
