From a recent prod issue, defensive copying is a solid tip for data integrity, but beware of larger arrays. It introduces performance/memory overhead. Consider alternatives like immutable views, lazy copies, or partial copying when size matters. Balance safety & efficiency!

Do you have a Java code where you can implement it using record feature in java

Thanks for sharing that. I wander in which case we want to avoid the defensive copy? Should we be concerned about the memory usage of it? Or should we apply this all the time?

Is your tutorial still using public class HelloWorld and 50-line POJOs? You may be learning a version of Java that's a decade old. codebysophy shows us what #Java26 actually looks like in 2026.

Demo of what I think is the future of programming for many, many of us. Markdown notebooks! When coding is happening through specs, long prompts, and .md files to interact with coding agents, we need an editor to support that! LLMs produce markdown en masse and I am tired of copy-pasting those things. Jupyter is clunky for copy-pasting and is somewhat foreign to LLMs. Code editors are becoming less relevant as I get into the files less and less.
