I've got a string in Java: Acidum acetylsalic. Acid.ascorb, Calcium which I want to split. The string has to be cut after every space preceded by a dot or colon: ,[space] or .[space]

In result I need three strings: Acidum acetylsalic, Acid.ascorb, Calcium

I know I need some regex and according to this and this I tried "\, |\. " but I doubt that's not how regex work.

  • replace all dot or commas with commas or dots then split your string – John Pangilinan Dec 29 '15 at 07:29

Split by

"[,.] "

[,.] - character set with one comma or dot

The problem with your original regex is that you need to escape the dot once to make it a literal dot and a second time to escape the slash escaping it. It will also work if you change it to: 
", |\\. "

Try this:

str.split("[\\.,]\\s")

Use split("(\.\s)|(\,\s)")

You need to encode special characters see https://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html

Try this

    String str="Acidum acetylsalic. Acid.ascorb, Calcium";

    String[] resStr= str.split("[.,][\\s]");

    for (String res : resStr) {

        System.out.println(res);
    }

Output :

Acidum acetylsalic
Acid.ascorb
Calcium
