String Split in Scala in Scala

In Scala, you can split a string into an array of substrings using split(). It takes a regular expression as the delimiter:

s.split(regex)   // splits using a regex delimiter

Here are some examples:

val sentence = "hello world foo"
val words = sentence.split(" ")
// words == ["hello", "world", "foo"]

val csv = "a,b,c"
val parts = csv.split(",")
// parts == ["a", "b", "c"]

You can loop through the resulting array:

for (w <- words) {
    println(w)
}
