Understanding the Prototype Design Pattern in Java
The Prototype Design Pattern is a creational design pattern that involves creating new objects by copying existing ones, known as prototypes. It is especially useful when object creation is costly or complex, and there is a need to avoid the overhead of recreating objects from scratch. In this post the Prototype Pattern is explained with practical examples including object cloning and registry of prototypes. What is the Prototype Design Pattern? The Prototype Pattern allows objects to create copies of themselves. This eliminates the need for the client to know the details of object creation and helps in duplicating objects efficiently. When to Use Prototype Pattern When the cost of creating a new object is expensive or complex. When you want to avoid subclasses for object creation. When objects need to be created dynamically at runtime. Key Components Prototype Interface: Declares a method for cloning itself, typically a clone() method. Concrete Prototype...
