why cant the java find the file code example

Example: java cannot find file path

public static void main(String[] args) {


            Scanner scanner = new Scanner(ScannerReadFile.class.getResourceAsStream("CardNative.java.txt"));

            while (scanner.hasNextLine()) {
                String line = scanner.nextLine();
                System.out.println(line);
            }
            scanner.close();

    }
}
