 The above is a simple example of using the consumer. Configuration for the consumer is supplied with a `java.util.Properties`

 demonstrates consuming a single Kinesis stream in the AWS region "us-east-1". The AWS credentials are supplied using the basic method in which
 the AWS access key ID and secret access key are directly supplied in the configuration (other options are setting
-`ConsumerConfigConstants.AWS_CREDENTIALS_PROVIDER` to `ENV_VAR`, `SYS_PROP`, `PROFILE`, `ASSUME_ROLE`, and `AUTO`). Also, data is being consumed
+`AWSConfigConstants.AWS_CREDENTIALS_PROVIDER` to `ENV_VAR`, `SYS_PROP`, `PROFILE`, `ASSUME_ROLE`, and `AUTO`). Also, data is being consumed
 from the newest position in the Kinesis stream (the other option will be setting `ConsumerConfigConstants.STREAM_INITIAL_POSITION`
 to `TRIM_HORIZON`, which lets the consumer start reading the Kinesis stream from the earliest record possible).
