java regex match a string

Here is a string

* '''A happy man is too satisfied with the present to dwell too much on the future.'''
** "My Future Plans" an essay written at age 17 for school exam (18 September 1896) ''The Collected Papers of Albert Einstein'' Vol. 1 (1987) Doc.22

I need to get the text which starts with only one * till the end of that line

Pattern pattern = Pattern.compile("\\*(.+?)\\n");
    Matcher matcher = pattern.matcher(text);
    List<String> s = new ArrayList<String>();
    while (matcher.find()) {
        s.add(matcher.group(1));
    }

I tried the above code, but it matches even 2 * and also the text from * to new line is not coming up properly, what am I missing here?

which will make some sense i think,

Pattern pattern = Pattern.compile("^(\\*[^*].+)");

You can try this:

Pattern pattern = Pattern.compile("(?m)^\\*([^*].*)");

(?m) set the pattern in multiline mode where ^ means "begining of the line"

Adding \\n at the end is useless since the dot can't match a newline. (it's the reason why a lazy quantifier is useless too)
