What is method overloading and method overriding 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 the difference between method overloading and method override?

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.

What is meant by method overloading?

In other words, we can say that Method overloading is a concept of Java in which we can create multiple methods of the same name in the same class, and all methods work in different ways. When more than one method of the same name is created in a Class, this type of method is called Overloaded Method.

What is difference between overloading and overriding in C++?

In this article, we will learn about function overloading and function overriding in C++….Difference between Function Overloading and Function Overriding.

Basis	Function Overloading	Function Overriding
Number of times	A function can be overloaded multiple times	A function is overridden single time in its derived class

What feature allows different methods?

Answer: Overloading allows different methods to have same name, but differentsignatures where signature can differ by number of input parameters or typeof input parameters or both. Overloading is related to compile time (or static) polymorphism.

What is inheritance method?

Inheritance is a mechanism in which one class acquires the property of another class. For example, a child inherits the traits of his/her parents. With inheritance, we can reuse the fields and methods of the existing class. Hence, inheritance facilitates Reusability and is an important concept of OOPs.

Can We override the overloaded method?

Yes , since the overloaded method is a completely different method in the eyes of the compiler. It depends what you mean. A method can be an override for an overloaded method in a superclass. And you can overload a method that you are simultaneously overriding using another method.

What is the use of method overloading?

Overloading is a concept used to avoid redundant code where the same method name is used multiple times but with a different set of parameters. The actual method that gets called during runtime is resolved at compile time, thus avoiding runtime errors.

Can a main method be overloaded?

Yes, main method can be overloaded. Overloaded main method has to be called from inside the “public static void main(String args)” as this is the entry point when the class is launched by the JVM. Also overloaded main method can have any qualifier as a normal method have.

Is method overloading considered polymorphism?

Java, like many other object-oriented programming languages, allows you to implement multiple methods within the same class that use the same name but a different set of parameters. That is called method overloading and represents a static form of polymorphism .
