Scala Map addString() method with example
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:
object GfG
{
def main(args : Array[String])
{
val m 1 = Map( "geeks" - > 5 , "for" - > 3 , "cs" - > 2 )
val result = m 1 .addString( new StringBuilder())
println(result)
}
}
|
Output:
geeks -> 5for -> 3cs -> 2
Example #2:
object GfG
{
def main(args : Array[String])
{
val m 1 = Map( "geeks" - > 5 , "for" - > 3 , "cs" - > 2 , "geeks" - > 5 )
val result = m 1 .addString( new StringBuilder())
println(result)
}
}
|
Output:
geeks -> 5for -> 3cs -> 2
So, we can see here that the identical keys are only taken one time.
