Scala Mutable SortedMap dropWhile() method with example

Scala Mutable SortedMap addString() method with example

Last Updated : 04 May, 2020

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

Method Definition: def addString(b: StringBuilder): StringBuilder Return Type: It returns the elements in the String Builder.

Example #1:

Scala

// Scala program of addString()
// method
import scala.collection.SortedMap

// Creating object
object GfG
{ 

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

Output:

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

Example #2:

Scala

// Scala program of addString()
// method
import scala.collection.SortedMap

// Creating object
object GfG
{ 

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

Output:

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

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