WebDynamic method dispatch is the mechanism in which a call to an overridden method is resolved at run time instead of compile time. This is an important concept because of how Java implements run-time polymorphism. Java uses the principle of ‘a superclass reference variable can refer to a subclass object’ to resolve calls to overridden methods at run time. WebStart Learning View all courses. If a body of the method at runtime is bonded to a method call then it is called dynamic binding or late binding. This is because the method’s … Polymorphismallows an object to take multiple forms – when a method exhibits polymorphism, the compiler has to map the name of the method to the final implementation. If it's mapped at compile time, it's a static or early binding. If it's resolved at runtime, it's known as dynamic or late binding.
