Scala Map addString() method with example
  • Last Updated : 13 Aug, 2019

The addString() method is utilized to add the elements of the map to the String Builder.

Method Definition: def addString(b: StringBuilder): StringBuilder

Return Type: It returns the elements in the String Builder.

Example #1:




// Scala program of addString()
// method
  
// 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
        val result = m1.addString(new StringBuilder()) 
          
        // Displays output
        println(result)
      
    }
}
Output:



geeks -> 5for -> 3cs -> 2

Example #2:




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

So, we can see here that the identical keys are only taken one time.
