Amazon Elastic Transcoder - How to get the preset using name

I need to get the Preset from the List (System Presets). If I get the Preset with name like the following, it will returns the first Preset. But I need to get PresetId with name "System preset: Generic 320x240".

BasicAWSCredentials creds = new BasicAWSCredentials(accessKey, secretKey);
AmazonS3 s3Client = AmazonS3ClientBuilder.standard()
                                .withCredentials(new AWSStaticCredentialsProvider(creds)).build();
AmazonElasticTranscoder amazonElasticTranscoder = AmazonElasticTranscoderClientBuilder.standard()
                                .withCredentials(new AWSStaticCredentialsProvider(creds)).withRegion(s3Client.getRegionName())
                                .build();
List<Preset> presets = amazonElasticTranscoder.listPresets().getPresets();
String presetId = presets.iterator().next().withName("System preset: Generic 320x240").getId();

The above code returns "1351620000001-000001" instead of "1351620000001-000061"

my pom.xml,

I am trying to get the all Presets from AWS Elastic Transcoder but the following code returns only 50 out of 62

List<Preset> presets = amazonElasticTranscoder.listPresets().getPresets();

How to get the Preset dynamically using java? How to get all the Presets (include Custom presets) as well.
