Scala Mutable SortedMap addString() method with a separator with example
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 SortedMap in the String Builder and a separator is also added between the elements of the SortedMap.
Example #1:
import scala.collection.SortedMap
object GfG
{
def main(args : Array[String])
{
val m 1 = SortedMap( "geeks" - > 5 , "for" - > 3 , "cs" - > 2 )
val result = m 1 .addString( new StringBuilder(), "_" )
println(result)
}
}
|
Output:
cs -> 2_for -> 3_geeks -> 5
Example #2:
import scala.collection.SortedMap
object GfG
{
def main(args : Array[String])
{
val m 1 = SortedMap( "geeks" - > 5 , "for" - > 3 , "geeks" - > 2 )
val result = m 1 .addString( new StringBuilder(), "_" )
println(result)
}
}
|
Output:
for -> 3_geeks -> 2
So, here the identical keys are removed.
