Answer 1

split method takes regular expression as input. The pipe is a special character for regular expression, so if you want to use it tou need to escape the special character. Ther are multiple solutions:

You need to escape the "pipe" character

str.split("\\|");

Or you can use the helper quote:

str.split(Regexp.quote("|"))

Or between sqares:

str.split("[|]");
