import java.util.regex.Pattern;
import java.util.regex.MatchResult;
import java.util.Arrays;

public class Main {

    public static void main(String []args) {
        // Validate mac address
        boolean isMatch = Pattern.compile("^(?:[0-9A-Fa-f]{2}[:-]){5}(?:[0-9A-Fa-f]{2})$")
               .matcher("00:00:5e:00:53:af")
               .find(); 
        System.out.println(isMatch); // prints true
        
        // Extract mac address from a string
        String[] matches = Pattern.compile("(?:[0-9A-Fa-f]{2}[:-]){5}(?:[0-9A-Fa-f]{2})")
                          .matcher("Unknown error in node 00:00:5e:00:53:af. Terminating.")
                          .results()
                          .map(MatchResult::group)
                          .toArray(String[]::new);
        System.out.println(Arrays.toString(matches)); // prints [00:00:5e:00:53:af]
