Java – Split string into a list of numers or characters

If I have say "ic182nob2"
I would like to split that into an array list string of

["i","c", "182", "n", "o", "b", "2"]

I tried the split string with regex, but i ended up getting "ic", "182", "nob", "2" which is not what i want

>Solution :

We can try splitting on the regex alternation (?<=\\D)|(?=\\D):

String input = "ic182nob2";
String[] parts = input.split("(?<=\\D)|(?=\\D)");
System.out.println(Arrays.toString(parts));  // [i, c, 182, n, o, b, 2]

The above logic makes a split when either the preceding or following character is not a digit:

(?<=\\D)  what precedes is not a digit
|         OR
(?=\\D)   what follows is not a digit
