Static Binding vs Dynamic Binding

Static Binding

• Static Binding occurs at compile time. Compiler decides the type to be bound in compilation process.
• Private, final, static methods and variables uses static binding
• Static binding uses Type information for binding
• Overloaded methods are bonded using static binding
• Internally it is required to determine the following facts for static binding mainly by the compiler
• Definition/ Declaration/ Scope
• Binding is happened considering the above aspects while compilation.

Dynamic Binding

• Dynamic binding occurs during Run-time.
• Virtual methods are bonded during run-time based upon run-time object.
• Dynamic binding uses Object to resolve binding.
• Overridden methods are bonded using dynamic binding at run-time.
• Internally it is required to determine the following facts for dynamic binding mainly by the runtime
• Activation/ Binding /Lifetime
