Java: Upcasting and Dynamic Dispatch
Answer
It is the process where the JVM determines the method to invoke at runtime.
Dynamic method dispatch allows Java to implement polymorphism by selecting which method to run at runtime based on the object's actual type. For example, if `Product p = new Book();`, calling `p.display()` will invoke the `display()` method in `Book`, not `Product`, because `Book` is the runtime type.
