針對(duì)您的情況使用此正則表達(dá)式：

From:\s+([\w-]+@([\w-]+\.)+[\w-]+)

我已經(jīng)用https://www.freeformatter.com/java-regex-tester.html#ad-output嘗試了這個(gè)正則表達(dá)式，它符合您的要求。

String emailRegex = "[^\\s]+"; // Replace with a better one

Matcher m = Pattern.compile("(?m)^From:\\s*(" + emailRegex + ")\\s*$").matcher(yourString);

List<String> allMatches = new ArrayList<String>();

while(m.find())

System.out.println(m.group(1));

String test = " Sent: Tue Mar 05 15:42:11 IST 2019 "

String emailRegex = "[a-zA-Z0-9._%+-]+@[A-Za-z0-9.-]+\\.[a-zA-Z]{2,6}";

Pattern pattern = Pattern.compile("From\\:\\s(" + emailRegex + ")");// From\\:\\s same as Form : and () here i added Email Id regex or you also change to (.*\n) but not recommended

Matcher match = pattern.matcher(test);

while (match.find()) {

System.out.println(match.group(1));

}

輸出：

xtest@xyz.co.in

ytest@xyz.com

ytest@xyz.co.in
