What do you mean by new Kafka Producer? Do you just want to consume data and publish into another topic with some processing done?

You can't create a KafkaProducer from a KafkaConsumer instance.
You have to explicitly create a KafkaProducer using the same connection settings as your producer.
Considering the use case you mentioned (copying data from a topic to another), I'd recommend using Kafka Streams. There's actually an example in Kafka that does exactly that: https://github.com/apache/kafka/blob/trunk/streams/examples/src/main/java/org/apache/kafka/streams/examples/pipe/PipeDemo.java

i use consumer .seek method to start printing the data from specific offset but -1 and 0 offset value printing by default that is why iam trying to use to use new producer and send the data in new topic after applying if loop condition that'is my agenda if iam wrong then please give me solution.

Current limitation is, Source and destination cluster should be same with Kafka Streams.
Otherwise you need to use Processor API to define another destination cluster.
Another approach, is simply define a producer in the consumer program. Wherever your rule matches(based on offset or any conditions), call producer.send() method
