String streamName = "myStream";
DescribeStreamRequest describeStreamRequest = new DescribeStreamRequest();
describeStreamRequest.setStreamName(streamName);
System.out.println("descStream: " + JsonUtils.objToJson(dic.describeStream(describeStreamRequest)));

The returned stream details are as follows:

descStream: DescribeStreamResult [streamId=JnYbsMfWNn81e8n2mOC, streamName=myStream, createTime=1540977519187, lastModifiedTime=1540977519983, retentionPeriod=24, status=RUNNING, streamType=ADVANCED, dataType=BLOB, writablePartitionCount=2, readablePartitionCount=2, partitions=[PartitionResult{partitionId='shardId-0000000000', hashRange='[0 : 4611686018427387902]', status='ACTIVE', parentPartitionIds='null', sequenceNumberRange='[0 : 13286444]'}, PartitionResult{partitionId='shardId-0000000001', hashRange='[4611686018427387903 : 9223372036854775807]', status='ACTIVE', parentPartitionIds='null', sequenceNumberRange='[0 : 13288589]'}], hasMorePartitions=false, updatePartitionCounts=null]
