How to split a String at all special characters except dot?

Question

String line="word,1.2;3.1!4.5";

What regex should I use in Split(...) to remove all special characters except dot? (I need the dot to keep double and float values)

Answer 1

You may try this,

string.split("[^.\\w]");

or

string.split("[^.a-zA-Z\\d]");

Add + after the character class, if you want to apply split on one or more characters.

Answer 2

试试这个代码

line.split("[.\w]");

Answer 3

(?!\\.)\\W

You can also use this.See demo.
