Coding Tip 136: What is a defensive copy? #Java #JavaCodingTip #JavaCoding

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?

Explaining copy with coffee 😂 Java is my coming from where I live (island). And we have produce great coffee too! What kind of coffee you are drinking?
