How do I split a string by special characters, but without removing them?

Question

How do I split a string like (int,x) into [(, int, , x, )]

You mean like `str.split("");`? This will split on every character — GBlodgett, Jan 16 '19 at 04:21
you need to add more explanation to your question & illustrate by an example by taking a sample input & expected output. — Sabir Khan, Jan 16 '19 at 04:22
Please show your attempt at solving the problem, define what you mean exactly by special characters (is `_` also a special character for example) and tell what should happen if there are multiple of these special characters next to each other, e.g. `(int,,x)` — Jerry, Jan 16 '19 at 07:50

With your expected output, you can use \b to split your string and get the expected output,

Here is the Java code,

String s = "(int,x)";
System.out.println(Arrays.toString(s.split("\\b")));

Prints,

[(, int, ,, x, )]

@KhalidShah: Changed the code to Java and Java is my main language :) I got so used to python here as comparatively people using Python are more than Java now :) But more happy to post a code in my mother language :) – Pushpesh Kumar Rajwanshi Jan 16 '19 at 04:39

upvoted - took me 20 lines of code to do this without regex :( – Kartik Jan 16 '19 at 04:46
@Kartik: Thanks for upvote and exactly this is where regex helps :) – Pushpesh Kumar Rajwanshi Jan 16 '19 at 04:48
