Java Regex Metacharacters -


i found this thread , 1 of users on posted following line of code:

string[] digits2 = number.split("(?<=.)");

i have consulted couple of sources- 1 , 2-to decipher code mean can't figure out. can explain argument in split() method means?

edit: has same question had, here's helpful link

this positive lookbehind. overall expression means "after character, without capturing anything". essentially, if string looks like

abc

then matches occur @ |, between characters.

a|b|c|
