Remove white spaces in scala-spark - scala

Question

I have sample file record like this
2018-01-1509.05.540000000000001000000751111EMAIL#AAA.BB.CL
and the above record is from a fixed length file and I wanted to split based on the lengths
and when I split I am getting a list as shown below.
ListBuffer(2018-01-15, 09.05.54, 00000000000010000007, 5, 1111, EMAIL#AAA.BB.CL)
Everything looks fine until now . But I am not sure why is there extra-space adding in each field in the list(not for the first field).
Example : My data is "09.05.54",But I am getting as" 09.05.54" in the list.
My Logic for splitting is shown below
// Logic to Split the Line based on the lengths
def splitLineBasedOnLengths(line: String, lengths: List[String]): ListBuffer[Any] = {
var splittedLine = line
var split = new ListBuffer[Any]()
for (i <- lengths) yield {
var c = i.toInt
var fi = splittedLine.take(c)
split += fi
splittedLine = splittedLine.drop(c)
}
split
}
The above code take's the line and list[String] which are nothing but lengths as input and gives the listbuffer[Any] which has the lines split according to the length.
Can any one help me why am I getting extra space before each field after splitting ?

Answer 1

There are no extra spaces in the data. It's just adding some separation between the elements when printing them (using toString) to make them easier to read.
To prove this try the following code:
split.foreach(s => println(s"\"$s\""))
You will see the following printed:
"2018-01-15"
"09.05.54"
"00000000000010000007"
"5"
"1111"
"EMAIL#AAA.BB.CL"
