What is the best way to get continuous tick data?

Apparently, the code in the example does not work and I think it should be updated. Here is what I have:

while (true) {
            try {

                ExchangeWebsocketClient exchangeWebsocketClient = ExchangeClientFactory.websocket(ExchangeVendor.BINANCE);

                List<CurrencyPair> targetPairs = Collections.singletonList(CurrencyPair.parse("BTC", "USDT"));
                Flux<TickData> tickDataFlux = exchangeWebsocketClient.createTradeWebsocket(targetPairs);
//                .doOnNext(tickData -> System.out.println(tickData.getQuantity()))
//                .subscribe();
                while (true) {
                    TickData tickData = tickDataFlux.blockFirst();
                    System.out.println("time: " + System.currentTimeMillis());
                    System.out.println(tickData.getPrice());
                    System.out.println(tickData.getQuantity());
                    System.out.println("=======================");
                }
            } catch (Exception e) {
                StringWriter stringWriter = new StringWriter();
                    PrintWriter printWriter = new PrintWriter(stringWriter);
                    e.printStackTrace(printWriter);
                    testLogger.info(stringWriter.toString());
                    testLogger.info(e.getMessage());

            }
        }

Sorry if it should be obvious. I am a noob.
