Java 22-26: The Trajectory Beyond 21

What's shipped since the Java 21 baseline: unnamed variables and patterns, Stream Gatherers moving from preview to finalized, primitive types joining pattern matching, and a look at Java 25 as the next LTS and Java 26 as the current bleeding edge -- framed as a trajectory to track rather than a frozen list of facts.

Learning objectives

  • Use unnamed variables (_) and unnamed patterns to discard values you don't need in a pattern match
  • Explain what a Stream Gatherer is and what gap it fills that map/filter/reduce/collect couldn't
  • Describe the direction primitive types in patterns is heading and why it closes a gap record patterns left open
  • Explain why Java 25 is the next LTS worth planning a migration toward
  • Approach any feature described as 'latest' or 'preview' with the right amount of confidence versus caution
