Last Updated :

This method is same as addString() method but here a start, a separator and an end is also included.
Method Definition: def addString(sb: mutable.StringBuilder, start: String, sep: String, end: String): mutable.StringBuilder
Where, sep is the separator stated.
Return Type: It returns the elements of the map in the String Builder and a start, a separator and an end is also included here.
Example #1:
object GfG
{
def main(args : Array[String])
{
val m 1 = Map( "geeks" - > 5 , "for" - > 3 , "cs" - > 3 )
val result = m 1 .addString( new StringBuilder(), ">>>" , "|" , "--" )
println(result)
}
}
|
Output:
>>>geeks -> 5|for -> 3|cs -> 3--
Example #2:
object GfG
{
def main(args : Array[String])
{
val m 1 = Map( "geeks" - > 5 , "for" - > 3 , "for" - > 3 )
val result = m 1 .addString( new StringBuilder(), ">>>" , "|" , "--" )
println(result)
}
}
|
Output:
>>>geeks -> 5|for -> 3--
So, here the identical keys are removed.
