java - Split a string with multiple delimiters while keeping these delimiters -

let's have string:

string x = "a| b |c& d^ e|f"; 

what want obtain looks this:

a | b | c  &  d ^ e | f 

how can achieve using x.split(regex)? namely regex?

i tried link: how split string, keep delimiters?

it gives explanation on how 1 delimiter. however, using , modifying fit multiple delimiters (lookahead , lookbehind mechanism) not obvious not familiar regex.

the regex splitsplitting on optional spaces after word boundary

\\b\\s* 

note \\b checks if preceding character letter, or digit or underscore, , matches number of whitespace characters string split on.

here sample java code on ideone:

string str = "a| b |c& d^ e|f"; string regex = "\\b\\s*"; string[] spts = str.split(regex);     for(int =0; < spts.length && < 20; i++)     {         system.out.println(spts[i]);     }
