Java: Regular expression, how to?

Hello Experts,

can a regular expression locate two patterns in the same line? see code below

public class RegularExpression {

	public static void main(String[] args) {
		// log source
		String source = "12:22:22.826 message QueueRoute to 5554443322 \n"  +
				"12:22:22.926 message AddRoute to queue 65 \n" +
				"12:22:23.126 message CancelRoute to queue 45 \n" +
				"";		

		Pattern timePattern = Pattern.compile("\\d{2}:\\d{2}:\\d{2}\\.\\d{3} && (Queue\\w+)"); //this also works		
		Matcher timeMatcher = timePattern.matcher(source);
		while (timeMatcher.find()) {
			System.out.println(timeMatcher.group());
		}

	}// END OF MAIN

}// END OF CLASS

in other words, if time and word found, do something...

Why not just define two Patterns and check if both (or either) of them match?

It has to find a timestamp followed by any number of characters and then the word Queue with at least one 'word' character after it. And then it prints the time stamp and the Queue word.

Sure, have them separated by .* (i.e., zero or more characters)


something like:

Pattern timePattern = Pattern.compile("\\d{2}:\\d{2}:\\d{2}\\.\\d{3}.*(Queue\\w+)");
