Access PCollection contents

[amir bahmanyari]

Hi Colleagues,I receive data fro KafkaIO bounded source as 
:PCollection<KafkaRecord<byte[],byte[]>> kafkarecords = 
p.apply(KafkaIO.read().withBootstrapServers("kirkhost:9092").withTopics(topics).withMaxNumRecords(10));
 
How do I print out and/or access the records one at a time as String?Thanks for 
your help.Amir
