I have a String which contains multiple url inside like: "https://example.org,http://example.net". The URL will be splited by the comma sign ",".

Normally I can split them using the syntax: split("\\s*,\\s*") but the url might contain the comma sign so I would like to split them when I get the ",http" syntax in the URL, so I use: split("\\s*,http\\s*"), but then from my second URL the "http" will be get rid of my URL string.

Can any one give me a hint to split the URL here in my string? Thank you so much!

Use a lookahead, `split("\\s*,\\s*(?=http)")` – Wiktor Stribiżew Apr 16 '18 at 10:16
I see, thank you so much Wiktor! – Bali Apr 16 '18 at 10:18
But if you are dealing with URLs that can contain commas (is that even possible?), how do you know that you will never come across an URL that has `,http` somewhere in the middle? – anothernode Apr 16 '18 at 10:20
yes, in my url they can contain comma, something like: https://example.org?key=value1,value2 – Bali Apr 16 '18 at 10:26
You'll get in trouble then if your code ever has to deal with something like `http://foo.com?key1=value1,http=value2`. Unlikely maybe, but I'd think twice before I'd take that risk. – anothernode Apr 16 '18 at 10:31
this would be one possibility, thank you for your hint ;) – Bali Apr 16 '18 at 10:58
