![]() ![]() Static and final methods cannot be overridden.įrom the above table, we can see that the rules of overriding are more restrictive than overloading. Only inherited methods can be overridden. Which method to invoke is decided at compile time. Which method to invoke is decided at runtime. Must not have more restrictive access modifiers. Must not throw new or broader checked exceptions. Provide multiple versions of a method with different signatures. 12 Rules of Overriding in Java You Should Knowįor the comparison, the following table gives us the similarities and differences between overriding and overloading methods:Ī subclass re-implements methods inherited from a superclass.What is Overloading in Java and Examples.For details about each, see the following articles: This article provides some comparisons between these two techniques. ![]() ![]() In the Java programming language, both overriding and overloading mean re-using method name, but they are quite different.

Overriding concerns defining a different implementation of the same method in inherited classes. Overloading concerns giving a method with the same name different parameters.Overriding is determined at runtime and is dynamic. Overloading is determined at compile time and is static.Here we have compared two forms of polymorphism in C#, overloading and overriding. The application checks at runtime what the type of the class is (Dog or YappyDog) and calls the method for that particular type. ![]() Here the base Dog class still uses it's own implementation, but the inherited YappyDog has it's own overridden implementation that it uses. YappyDog.Woof() // prints Woof! Woof! Woof! ![]()
