Difference Between Static And Dynamic Binding In Java
In Java, static binding or early binding refers to the process of associating a method call with its method definition at compile time based on the type of the reference variable, whereas dynamic binding or late binding occurs at runtime and selects the appropriate method implementation based on the actual object type. Static binding is typically used for static, private, and final methods, while dynamic binding is used for overridden methods in inheritance hierarchies. Static binding is faster and efficient, but dynamic binding allows for flexibility and polymorphism, making Java an object-oriented programming language.

1 - Static binding in Java refers to the process where the compiler determines the method or variable to be called during compile time based on the reference type. This is also known as early binding. On the other hand, dynamic binding is the process where the method or variable to be called is determined during runtime based on the actual object type. This is also known as late binding.
2) Static binding is achieved in method overloading, where the method signature is used to determine which method to call during compile time. In dynamic binding, method overriding is used, where the actual object type determines which method to call during runtime.
3) Static binding is faster than dynamic binding as the method resolution is done during compile time, resulting in better performance. Dynamic binding incurs some overhead during runtime as the method resolution is done dynamically.
4) Static binding is used for static methods, private methods, and final methods, as they cannot be overridden. Dynamic binding is used for instance methods that can be overridden in subclasses.
5) Static binding is also known as compile time polymorphism, whereas dynamic binding is known as runtime polymorphism.
6) Static binding is less flexible compared to dynamic binding, as it does not adapt to changes in the object type hierarchy during runtime.
7) In Java, static binding is the default behavior for overloaded methods, whereas dynamic binding is the default behavior for overridden methods.
8) Understanding the difference between static and dynamic binding is essential for Java developers to design efficient and flexible object oriented programs.
9) Our training program will cover in depth concepts of static and dynamic binding in Java, providing real world examples and hands on exercises to help students master this important aspect of Java programming.
