What is method overloading and method overriding in Java with example?
Overloading vs Overriding: Difference between Method Overloading and Method Overriding
|Method Overloading||Method Overriding|
|Is an example of compile-time polymorphism||It is an example of runtime polymorphism|
|Return type can be different but you must change the parameters as well.||Return type must be same in overriding|
What is method overriding and method overloading?
In the method overloading, methods or functions must have the same name and different signatures. Whereas in the method overriding, methods or functions must have the same name and same signatures. 2. Method overloading is a example of compile time polymorphism.
What is the difference between method overriding and overloading?
Overloading occurs between the methods in the same class. Overriding methods have the same signature i.e. same name and method arguments. Overloaded method names are the same but the parameters are different. With Overloading, the method to call is determined at the compile-time.
What is the purpose of method overloading in Java?
Overloading in Java is the ability to define more than one method with the same name in a class. The compiler is able to distinguish between the methods because of their method signatures. This term also goes by method overloading, and is mainly used to just increase the readability of the program; to make it look better.
What are the advantages of method overriding in Java?
Method overriding is an example of run time polymorphism in java.
What is meant by method overriding in Java?
Method overriding in Java programming occurs when the method in the subclass has the same return type, or parameters, name or signature as the parent class. Method overriding is the method by which Java can support runtime polymorphism.
What’s the point of method overloading?
Method Overloading is a feature that allows a class to have more than one method having the same name, if their argument lists are different. It is similar to constructor overloading in Java, that allows a class to have more than one constructor having different argument lists.
