In the 0.82 Producer API and 0.9 Consumer api you can use something like

Properties configProperties = new Properties();
configProperties.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG,"localhost:9092");
configProperties.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG,"org.apache.kafka.common.serialization.ByteArraySerializer");
configProperties.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG,"org.apache.kafka.common.serialization.StringSerializer");

org.apache.kafka.clients.producer.Producer producer = new KafkaProducer(configProperties);
producer.partitionsFor("test")
