I'm writing an application where I'm receiving a message that is a sequence of tag1=value1|tag2=value2|tag3=value3 etc. I want to split it around the | delimiter.
Having read the Javadoc there is nothing to say that the String.split(String regex) method is guaranteed to maintain the original order of the message. I've played about and it seems ok, but I'd rather not commit to this approach if I'm going to get caught out later.
So, does anybody know if there are any situations where the order of array elements returned by split() can be altered from the original String? Or can anyone point out any documentation that says the order is guaranteed to be maintained?
(Apologies if this is a dupe, but I can't find a similar question on the site.)

The split() method splits a string into an array of substrings. The split() method returns the new array.
Yes, . split() always preserves the order of the characters in the string.
The method split() splits a String into multiple Strings given the delimiter that separates them. The returned object is an array which contains the split Strings.
The string split() method breaks a given string around matches of the given regular expression. After splitting against the given regular expression, this method returns a string array.
The javadoc says:
The substrings in the array are in the order in which they occur in this string.
EDIT: the above is for the two-argument split(String regex, int limit) version, but the single-argument version
works as if by invoking the two-argument split method with the given expression and a limit argument of zero.

I'm seeing The substrings in the array are in the order in which they occur in this string. in http://docs.oracle.com/javase/7/docs/api/java/lang/String.html...
