The addString method utilized to append the elements of the Scala Iterator to a String Builder.This method is same as addString() method but here a start, a separator and an end is also included.
Method Definition: def addString(b: mutable.StringBuilder, start: String, sep: String, end: String): mutable.StringBuilder
Where, sep is the separator stated.
Return Type: It returns the elements of the Iterator in the String Builder and a start, a separator and an end is also included here.
Example #1:
Scala
object GfG
{
def main(args : Array[String])
{
val m 1 = Iterator( 1 , 3 , 4 , 8 )
val result = m 1 .addString( new StringBuilder(), " = >", "|", ".")
println(result)
}
}
|
Example #2:
Scala
object GfG
{
def main(args : Array[String])
{
val m 1 = Iterator( 1 , 3 , 3 , 8 )
val result = m 1 .addString( new StringBuilder(), " = >", "|", ".")
println(result)
}
}
|
So, here the identical element is not removed like in maps.
