Becoming One of the First Java 25 Certified Developers in the World (or Learning New Features)

Summary

Looking to learn about features in the language added after Java 21 in more detail? As programmers, we're used to dealing with edge cases. But what about edge cases in the language?

As certification book authors, we encounter lots of interesting and/or surprising behavior. After a brief overview of the cert, we'll explain these features and walk through tricky questions featuring functionality added to the language from Java 17 to Java 25. Plus there'll be coding practice to explore the new features.

Walk away with an increased awareness of these Java topics.
