Understanding State Pattern With Calculator Example
The State Pattern lets objects change behavior dynamically based on their internal state, making it ideal for handling complex, state-dependent behavior in a maintainable way.
Understanding the State Pattern with Calculator 🛠 Introduction The State Pattern allows an object to change its behavior dynamically based on its internal state. It’s a powerful design pattern for handling complex, state-dependent behavior in an organized and maintainable way. In this article, we’ll explore the State Pattern by implementing a simple Calculator with multiple states. 📚 Calculator State Example 1️⃣ State Interface The State interface defines the contract that all concrete state classes must implement. It contains methods that represent the state-specific behavior. public inter...
