Hello, I'm a developer. When I wanted to learn Kafka, I found the official website. I found that there was an error code, the target location
--> http://kafka.apache.org/documentation/#quickstart --> 1. GETTING STARTED --> 1.3 Quick Start --> STEP 7: PROCESS YOUR EVENTS WITH KAFKA STREAMS The following code KStream<String, String> textLines = builder.stream ("quickstart-events"); > > > KTable<String, Long> wordCounts = textLines > > .flatMapValues(line -> Arrays.asList ( line.toLowerCase ().split(" "))) > > .groupBy((keyIgnored, word) -> word) > > .count(); > > > wordCounts.toStream ().to("output-topic"), Produced.with ( Serdes.String > (), Serdes.Long ())); > There is an extra bracket after "output topic", when I click Kafka streams demo <http://kafka.apache.org/25/documentation/streams/quickstart> below But I don't know who the email was sent to, so I found this email and hope to optimize the page code. ----------------------------------------------- Name: 刘玉川 LiuYuChuan NickName: Lycos PostCode：510000 MobPhone：18615183765 TelePhone： QQ： 763999883 Addr: 广州市越秀区环市东路498号，柏丽商业中心 Baili commercial center, No. 498, Huanshi East Road, Yuexiu District, Guangzhou City, Guangdong Province
