Remove Characters from the end of a String Scala

How about using dropRight, which works in 2.8:-

"abc!".dropRight(1)

Which produces "abc"

string.init // padding for the minimum 15 characters

If you want the most efficient solution than just use:

str.substring(0, str.length - 1)

val str = "Hello world!"
str take (str.length - 1) mkString
