scala string.split does not work

Question

Following is my REPL output. I am not sure why string.split does not work here.

val s = "Pedro|groceries|apple|1.42"
s: java.lang.String = Pedro|groceries|apple|1.42

scala> s.split("|")
res27: Array[java.lang.String] = Array("", P, e, d, r, o, |, g, r, o, c, e, r, i, e, s, |, a, p, p, l, e, |, 1, ., 4, 2)

Answer 1

If you use quotes, you're asking for a regular expression split. | is the "or" character, so your regex matches nothing or nothing. So everything is split.

If you use split('|') or split("""|""") you should get what you want.
