Why method overloading is not possible by changing the return type of method only explain with proper Java programming example?

Q) Why Method Overloading is not possible by changing the return type of method only? In java, method overloading is not possible by changing the return type of the method only because of ambiguity.

Can we achieve method overloading by changing the return type of method?

No, you cannot overload a method based on different return type but same argument type and number in java.

What is the error if return type is changed in method overloading?

It would be a compiler error. The compiler does not consider the return type while differentiating the overloaded method. But you cannot declare two methods with the same signature and different return types. It will throw a compile-time error.

Can we change the return type in method overriding in java?

Java version 5.0 onwards it is possible to have different return types for an overriding method in the child class, but the child's return type should be a subtype of the parent's return type. The overriding method becomes variant with respect to return type.

Why function overloading does not depend on the return type?

Answer: No,It does not depend on Return Type. Because if return type is different and function name as well as parameter is also same. Then it will give compile time error.

Method Overloading in Java

What is function overloading which are the rules of function overloading Why return type is not considered in function overloading?

Function Overloading in C++

When a function name is overloaded with different jobs it is called Function Overloading. In Function Overloading “Function” name should be the same and the arguments should be different. Function overloading can be considered as an example of polymorphism feature in C++.

What is method overloading example?

In Java, two or more methods may have the same name if they differ in parameters (different number of parameters, different types of parameters, or both). These methods are called overloaded methods and this feature is called method overloading. For example: void func() { ... }

What will be the return type of overriding methods will it be same or varies?

The basic rule for overriding a method in Java is that the new overriding method in derived class should have same signature as of Base class's method. But there is on exception to this rule i.e. Overriding method can have different return type but this new type should be, A Non-Primitive.

Does return type matter in method overloading in Java?

Return type does not matter while overloading a method. We just need to ensure there is no ambiguity! The only way Java can know which method to call is by differentiating the types of the argument list.

What is the return type of method overriding?

An overriding method can also return a subtype of the type returned by the overridden method. This subtype is called a covariant return type. When overriding a method, you might want to use the @Override annotation that instructs the compiler that you intend to override a method in the superclass.

Why is method overloading not possible by changing the return type proof this with code snippet?

Overloading is the mechanism of binding the method call with the method body dynamically based on the parameters passed to the method call. ... It is not possible to decide to execute which method based on the return type, therefore, overloading is not possible just by changing the return type of the method.

Why overloading is not possible in C?

Function overloading is a feature of Object Oriented programming languages like Java and C++. As we know, C is not an Object Oriented programming language. Therefore, C does not support function overloading.

Which is incorrect about method overloading?

Answer: It will throw a compilation error: More than one method with same name and argument list cannot be given in a class even though their return type is different. Method return type doesn't matter in case of overloading.

Why method overloading is not possible by changing the return type of method only Mcq?

It is not possible to decide to execute which method based on the return type, therefore, overloading is not possible just by changing the return type of the method.

Does the return type of a function help in overloading a function?

The return type of a function has no effect on function overloading, therefore the same function signature with different return type will not be overloaded.

What is the difference between method overloading and method overriding in java?

In method overloading, methods must have the same name and different signatures. In method overriding, methods must have the same name and same signature.

Can overloaded functions have different return types C++?

Function overloading and return type in C++

The definition of the function must differ from each other by the types and/or the number of arguments in the argument list. You cannot overload function declarations that differ only by return type.

What is difference between overloading and overriding?

What is Overloading and Overriding? When two or more methods in the same class have the same name but different parameters, it's called Overloading. When the method signature (name and parameters) are the same in the superclass and the child class, it's called Overriding.

Can we override method in same class?

Therefore, you cannot override two methods that exist in the same class, you can just overload them.

Can we have different return type in method overriding in C#?

You cannot change the return type of method during overriding.

Why method overloading is used in Java?

Advantages of method overloading in java

Method overloading increases the readability of the program. Overloaded methods give programmers the flexibility to call a similar method for different types of data. Overloading is also used on constructors to create new objects given different amounts of data.

Why operator overloading is not possible in Java?

Java doesn't allow user defined operator overloading because if you allow programmer to do operator overloading they will come up with multiple meanings for same operator which will make the learning curve of any developer hard and things more confusing and messing.

Which methods Cannot be overloaded in Java?

Can we overload methods that differ only by static keyword? We cannot overload two methods in Java if they differ only by static keyword (number of parameters and types of parameters is the same).

What are the scenarios in which we can not perform function overloading?
