Splitting a Java String by the pipe symbol using split("|")
You need
test.split("\\|");split uses regular expression and in regex | is a metacharacter representing the OR operator. You need to escape that character using \ (written in String as "\\" since \ is also a metacharacter in String literals and require another \ to escape it).
You can also use
test.split(Pattern.quote("|"));and let Pattern.quote create the escaped version of the regex representing |.
Use proper escaping: string.split("\\|")
Or, in Java 5+, use the helper Pattern.quote() which has been created for exactly this purpose:
string.split(Pattern.quote("|"))which works with arbitrary input strings. Very useful when you need to quote / escape user input.
