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|         


        

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.
