I am absolutely stuck and stumped on this, ive tried everything to parse/process the live output. This is the output I recieve from a .jar application simulating live train data: Simulator output:

R: T1(R02, F), T2(R07, F), T3(R38, B), T4(R42, B)
Processing train data: R: T1(R02, F), T2(R07, F), T3(R38, B), T4(R42, B)

but then I keep getting this when I process it:

Processing train entry: T1(R02
Unrecognized train data format: T1(R02
Processing train entry: F)
Unrecognized train data format: F)

private void processTrainData(String line) {
System.out.println(“Processing train data: ” + line);

if (line.equals("Train positions:")) {
    return;
}

String[] sections = line.split(": ");
if (sections.length != 2) {
    System.err.println("Unrecognized train data format: " + line);
    return;
}

String[] trainData = sections[1].split(", ");
for (String train : trainData) {
    System.out.println("Processing train entry: " + train);

    // Regular expression to match train number, station code, and direction
    Pattern pattern = Pattern.compile("T(\d+)\((\w{3}), ([FB])\)");
    Matcher matcher = pattern.matcher(train);
    if (matcher.find()) {
        int trainNumber = Integer.parseInt(matcher.group(1));
        String stationCode = matcher.group(2);
        String direction = matcher.group(3).equals("F") ? "forward" : "backward";

        System.out.println("Train number: " + trainNumber);
        System.out.println("Station code: " + stationCode);
        System.out.println("Direction: " + direction);

        Point coordinates = trainMap.getStationCoordinates(stationCode);
        if (coordinates != null) {
            System.out.println("Parsed train data - Train number: " + trainNumber + ", coordinates: ("
                    + coordinates.x + ", " + coordinates.y + ")");
            trainPositions.put(trainNumber, coordinates);

            // Update the next train panel for the tracked train
            if (trainNumber == trackedTrainNumber) {
                Station currentStation = trainTracker.getStation(stationCode);
                SwingUtilities.invokeLater(() -> updateNextTrainStations(currentStation));
            }
        } else {
            System.err.println("No coordinates found for station: " + stationCode);
        }
    } else {
        System.err.println("Unrecognized train data format: " + train);
    }
}

}
and this is my code, why does it keep triggering the unrecognized train data format?
