What is the simplest method to remove the last character from the end of a String in Scala?
I find Rubys String class has some very useful methods like chop. I would have used "oddoneoutz".headOption in Scala, but it is depreciated. I don't want to get into the overly complex:
string.slice(0, string.length - 1) Please someone tell me there is a nice simple method like chop for something this common.

To remove the last three characters from the string you can use string. Substring(Int32, Int32) and give it the starting index 0 and end index three less than the string length. It will get the substring before last three characters.
To remove blank spaces from a string, Scala provides a trim() method. The trim() will remove spaces from both sides, i.e. before the characters(leading) and from the end(trailing). The method doesn't accept any parameter and returns a string with spaces removed from it.
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 love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
