Как можно упростить этот java код?

Dmitry Roo, еще немного ...

public class Main {

    private final static Pattern pattern = Pattern.compile("(?<left>\\d+)\\s(?<right>\\d+)");
    private final static String fileSuffix = ".txt";

    private final static String ifEqualMessage = "DRAW";

    private final static int defaultLimit = 5;
    
    @SuppressWarnings(value = "all")
    public static void main(String... args) throws Exception {
        //To set the limit when launching the application.
        var limit = getLimitFromArr(args);
        var inputFile = String.format("in.%s", fileSuffix);
        var outputFile = String.format("out.%s", fileSuffix);
        Files.lines(Paths.get(inputFile))
                .limit(limit) // Limit if needed
                .map(Main::parseToResult)
                .filter(Optional::isPresent)
                .map(Optional::get)

                                identity.right + accumulator.right))
                .map(Result::getResultAsString)

                        printWriter.write(s);
                    } catch (Exception ignored) {/*NooP*/}
                });
    }

    }

                            .replace("-1", ifRightIsBiggerMessage)
