Your Java isn't the same
In a recent survey, 85% of developers still use Java 8 or older. When Java 8 was released in 2014, changes would come in large quantities at each release. But when the release cadence changed to every six months, many developers could not follow the changes to the language. This presentation will cover the main changes to each version after Java 11 up to Java 20/21, including Variable Type Inference (var), Records, Switch expressions, Text Blocks, Sealed Classes, Hidden Classes, Pattern Matching, and much more.
Scaling Batch Processing Apps with Java
In the world of cloud-native apps, we need to deal with a large amount of data from multiple sources. This requires considerable effort to read, process, and distribute. As the number of records increases, plain Java may not be the best solution. With many out-of-the-box solutions—such as transaction management, retry, chunk processing, and several templates—the lightweight framework of Spring Batch can help. We discuss this universe and its architecture and templates—providing live code examples to demonstrate all possibilities you have on your hands.
