Understanding Flyweight Design Pattern in Java
The Flyweight Design Pattern is a powerful structural design pattern in Java used to reduce memory usage when dealing with a large number of similar objects. Instead of creating a new object every time, this pattern reuses shared objects , improving performance, memory efficiency, and scalability. If you work with applications like editors, games, data visualization tools, or map rendering, understanding the Flyweight Pattern is extremely useful. What is the Flyweight Pattern? The Flyweight Pattern allows an application to support a large number of fine-grained objects by sharing common data. It splits object state into: Intrinsic State – shared, reusable, constant Extrinsic State – specific to each object and supplied externally This allows the system to hold fewer objects in memory.
