Question

I have a string
” 11:45 AM, 12:30 PM, 04:50 PM “

I wish to extract the first time from this string using java regex.

I have created a java regex like :

“\d*\S\d*\s(AM|PM)” for this.

However i can only match this pattern in Java rather than extract it. How can i extract the first token using the Regex i created

Answer 1

The capturing parentheses where missing. Here is the code sample that should help you.

Pattern p = Pattern.compile("(\d*):(\d*)\s(AM|PM)");
Matcher m = p.matcher(str);
if (m.find()) {
    String hours = m.group(1);
    String minutes = m.group(2);
}
