This article explains the Prototype design pattern in Java, detailing its purpose, creation methods, implementation using Cloneable, example code with Person and ArrayList, Spring bean prototype usage, and discusses its advantages and drawbacks.
This article explains what Java shallow copy (shallow cloning) is, outlines its typical use cases, and provides step‑by‑step implementations using both the Object.clone() method and a manual cloning approach with clear code examples.
This article explains Java deep copy, its differences from shallow copy, key use cases such as data safety and avoiding shared state, and demonstrates three implementation methods—using Cloneable, serialization, and third‑party libraries like Guava—complete with runnable code examples.
This article explains the differences between shallow and deep copying in Java, illustrates how the Cloneable interface and the clone() method work, provides complete code examples for both copy types, and clarifies the concept of reference copying with diagrams and test outputs.
This article explains the Prototype creational design pattern, its definition, key concepts, typical usage scenarios, UML illustrations, and provides a complete Java implementation with code examples, output analysis, and a discussion of its application in Spring's prototype‑scoped beans.
This article explains Java object cloning, detailing why cloning is needed, how to implement shallow and deep copies using the Cloneable interface and serialization, and provides comprehensive code examples illustrating the differences and pitfalls of reference copying.
