The goal of Project Valhalla is to bring more flexible flattened data types to JVM-based languages, to bring the programming model back in line with the performance characteristics of modern hardware. The core feature is inline classes (known previously as value types ), but such a fundamental perturbation of the JVM…
Cramming may get a candidate a job. But they won’t succeed at the job if they don’t have the skills and experience needed.
