Java How to convert a String into an List?

I have a String, which can have an multiple number of words which are dot separated.

String s = "text.text1.text2.text3";

I want to generate a List which adds a Element for each word in the String.

List<String> list= Arrays.asList(s.split("/./")); generates just 1 Element.

Is there a fast way to do this?

Just the token is wrong, here is the correct code:

import java.util.*;

public class SeperateString {

    public static void main(String[] args) {
        String s = "text.text1.text2.text3";
        List<String> list= Arrays.asList(s.split("\\."));
        System.out.println(list);
    }

}

And here is the output:

[text, text1, text2, text3]

String#split is the way to go here, except that you want to split on the regex pattern \. by itself, as Java's regex API does not take delimiters:

String s = "text.text1.text2.text3";
List<String> elements = Arrays.asList(s.split("\\."));
System.out.println(elements);  // [text, text1, text2, text3]
