在定界符上拆分数组，但保留定界符的一部分

Question

I am trying to split a string on the follow delimiter }--{ , but I would like to keep the braces.

Example:

"{this}--{is}--{an}--{example}"  --> ["{this}","{is}","{an}","{example}"]

I can't split on the -- sequence on its own because some of the individual elements will have this sequence. Is this possible in Java?

Answer 1

Since you would like to keep part of the delimiter, put the parts that you would like to keep into lookahead and lookbehind , as follows:

String[] parts = str.split("(?<=\\})--(?=\\{)");

Demo.
