How to split a string, but also keep the delimiters?

Question

I have a multiline string which is delimited by a set of different delimiters:

(Text1)(DelimiterA)(Text2)(DelimiterC)(Text3)(DelimiterB)(Text4)

Answer 1

If you can afford, use Java's replace(CharSequence target, CharSequence replacement) method and fill in another delimiter to split with. Example: I want to split the string "boo:and:foo" and keep ':' at its righthand String.

String str = "boo:and:foo";
str = str.replace(":","newdelimiter:");
String[] tokens = str.split("newdelimiter");

Important note: This only works if you have no further "newdelimiter" in your String! Thus, it is not a general solution. But if you know a CharSequence of which you can be sure that it will never appear in the String, this is a very simple solution.
