Scala Map addString() method with a separator with example

  • Last Updated : 13 Aug, 2019

This method is identical to the addString() method but here a separator is also included.

Method Definition: def addString(b: StringBuilder, sep: String): StringBuilder

Where, sep is the separator stated.

Return Type: It returns the elements of the map in the String Builder and a separator is also added between the elements of the map.

Example #1:






// Scala program of addString()
// method with a separator
  
// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a map
        val m1 = Map("geeks" -> 5, "for" -> 3, "cs" -> 2)
          
        // Applying addString method
        // and a separator
        val result = m1.addString(new StringBuilder(), "_"
          
        // Displays output
        println(result)
      
    }
}
Output:
geeks -> 5_for -> 3_cs -> 2

Example #2:




// Scala program of addString()
// method with a separator
  
// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a map
        val m1 = Map("geeks" -> 5, "for" -> 3, "geeks" -> 2)
          
        // Applying addString method
        // and a separator
        val result = m1.addString(new StringBuilder(), "_"
          
        // Displays output
        println(result)
          
    }
}
Output:
geeks -> 2_for -> 3

So, here the identical keys are removed.
