📚 Topic Summary
Dynamic binding, also known as late binding, is a process in object-oriented programming where the specific method to be called is determined at runtime rather than at compile time. This allows for greater flexibility and polymorphism, as different objects can respond to the same method call in their own unique ways. Simulating this 'unplugged' means we'll explore this concept without writing code, using a hands-on activity to illustrate how objects decide which method to use.
In essence, dynamic binding is like having a set of instructions that can change depending on who's reading them. Instead of being fixed from the start, the instructions adapt to the specific object involved, making the system more adaptable and powerful.
