Java's use of memory, often chided for being excessive, is actually a strength as it trades more memory use for fewer CPU cycles. Java can only make this tradeoff due to its moving garbage collectors, something more memory efficient platforms often cannot. But what's the point in leaving available memory on the table if using it makes your program run faster? Efficient use of that resource wouldn't be to leave it untapped but to use it to speed up the program.

In this "Ask the Architect" episode of the Inside Java Podcast, recorded during JavaOne 2026, Nicolai Parlog talks to Ron Pressler, Java Architect at Oracle.

With JDK 27 introducing hybrid key exchange schemes that combine ML-KEM with traditional ECDHE algorithms, Java applications can gain TLS-layer protection against the harvest-now, decrypt-later threat without rewriting business logic.

In this episode of the Inside Java Newscast, Ana explains post-quantum hybrid key exchange for TLS 1.3 and demonstrates how a Java application can take advantage of it.

Flexible constructor bodies were added to Java 25 with JEP 513. In this episode of the Inside Java Newscast Billy Korando will review the issues with how constructors used to work before Java 25, either forcing developers to write convoluted code, or in some cases undermining the safety and integrity of child classes. Billy will then cover how flexible constructor bodies address these issues and how Java developers can use them to write safer code and better designed applications.
