i have tried wikifeed example with Kafka 2_12.1.0.0.the count method is now
depricated ,

previously in kafka_2.11-0.10.2.1 i have given count(localStateStoreName).

how to give the statestore name in Kafka 2_12.1.0.0.

i have attached the code below,
package kafka.examples.wikifeed;

import org.apache.kafka.clients.consumer.ConsumerConfig;
import org.apache.kafka.common.serialization.Serdes;
import org.apache.kafka.streams.KafkaStreams;
import org.apache.kafka.streams.KeyValue;
import org.apache.kafka.streams.StreamsBuilder;
import org.apache.kafka.streams.StreamsConfig;
import org.apache.kafka.streams.kstream.KStream;
import org.apache.kafka.streams.kstream.KTable;
import org.apache.kafka.streams.kstream.Produced;

import java.util.Properties;
