A significant percentage of production environments still use Java 8, exposing them to bugs, security vulnerabilities, and performance limitations.
An overview of popular JDK distributions like Amazon Corretto and Oracle, their varying support lifecycles, and what Long-Term Support (LTS) means for developers.
Java 11 introduced a modern HTTP client, new String and File methods for convenience, and support for TLS 1.3.
This period brought significant features like records for immutable data, sealed classes for controlled inheritance, and pattern matching for `instanceof` to reduce boilerplate.
Java 21 delivers major performance and concurrency improvements with virtual threads, alongside powerful new features like record patterns and sequenced collections.
Staying on a supported LTS version is critical for performance, security, and leveraging new language features that improve code quality and developer productivity.
The speaker answers audience questions about Java's relevance compared to other languages, missing features, and the impact of community involvement on a developer's career.
