Priority in regex manipulating

Question

I write some java code to split string into array of string. First, I split that string using regex pattern \"\\\\,\\\\,|\\\\,\" and then I split using pattern

Answer 1

How regex works: The state machine always reads from left to right. ,|,, == ,, as it always will only be matched to the first alternation:

_{(source: gyazo.com)}

,,|, == ,,?:

_{(source: gyazo.com)}

However, you should use ,,? instead so there's no backtracking:

_{(source: gyazo.com)}
