In modern software development, applications are expected to perform efficiently while managing resources effectively. Memory, in particular, is one of the most crucial resources. When building large-scale Java applications, memory consumption can quickly spiral out of control, especially when dealing with thousands of identical or similar objects. This is where the Flyweight Design Pattern becomes invaluable. It allows developers to reduce memory usage by sharing as much data as possible with similar objects, making it a fantastic choice for scenarios involving numerous, repeated instances. In this article, we’ll explore the Flyweight Design Pattern in Java, uncover its best practices, and discuss potential issues.
