Episode 57 “Make Java Safer with Flexible Constructor Bodies”

Posted on May 5, 2026



Flexible constructor bodies were added to Java 25 with JEP 513. In this episode of the Inside Java Podcast 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.
