You can have your key and value class each implement a known interface. Then you can assign or cast it.

KafkaConsumer consumerconsumer = new KafkaConsumer<>(PropertiesUtil.getPropsObj(configPath));

or

KafkaConsumer consumerconsumer1 = (KafkaConsumer) new KafkaConsumer(PropertiesUtil.getPropsObj(configPath));
