Why we Cannot overload function on the basis of return type?

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. Example: if there are two functions: int sum() and float sum(), these two will generate a compile-time error as function overloading is not possible here.

Why return type is not in method overloading in C#?

This kind of overloading would be ambiguous at best, so therefore it's not allowed.

Why we can not overload a function with return type?

You can't overload on return types as it is not mandatory to use the return value of the functions in a function call expression. GetVal(); What does the compiler do now? The compiler could just emit an "Ambiguous return type" message and refuse to compile.

Can we overload on the basis of return type?

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

Why return type is not in function overloading in java?

As said in previous answers, java does not support method overloading with different return type and same arguments. This is because, it has to determine which method to use at the compile time itself. To remove the ambiguity, they designed the method overloading technique like this.

Understanding function overloading concept: Return type of arguments | Sabaq Foundation

Does return type play any role while overloading a method justify?

Since return type of method doesn't matter while overloading a method.

Can we overload the main () method?

Yes, we can overload the main method in Java, but When we execute the class JVM starts execution with public static void main(String[] args) method.

Do function overloading expects the same return type or not?

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.

Can we override method with different return type?

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.

Can we overload method in different class?

Usually, method overloading happens inside a single class, but a method can also be treated as overloaded in the subclass of that class — because the subclass inherits one version of the method from the parent class and then can have another overloaded version in its class definition.

Which type of function Cannot be overloaded?

Functions that cannot be overloaded in C++

2) Member function declarations with the same name and the name parameter-type-list cannot be overloaded if any of them is a static member function declaration.

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++.

Can we change return type in method overloading in Java?

In java, method overloading is not possible by changing the return type of the method only because of ambiguity.

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.

Why we use overloading and overriding in C#?

Overloading is determined at compile time and is static. Overriding is determined at runtime and is dynamic. Overloading concerns giving a method with the same name different parameters. Overriding concerns defining a different implementation of the same method in inherited classes.

Can we overload the methods by making them static?

No, we cannot override static methods because method overriding is based on dynamic binding at runtime and the static methods are bonded using static binding at compile time. So, we cannot override static methods.

Is method overloading is possible by changing the return type of method?

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.

Can virtual function have different return type?

Yes. The return types are allowed to be different as long as they are covariant.

Can you distinguish between overloading and overriding method?

1. 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 overload and override main method?

The answer is, yes, we can overload the main() method. But remember that the JVM always calls the original main() method. It does not call the overloaded main() method.

Which method Cannot be overloaded in Java?

As per Java coding convention, static methods should be accessed by class name rather than an object. In short, a static method can be overloaded, but can not be overridden in Java.

Can we overload a constructor?

Constructors can be overloaded in a similar way as function overloading. Overloaded constructors have the same name (name of the class) but the different number of arguments. Depending upon the number and type of arguments passed, the corresponding constructor is called.

Can overloaded methods have different access modifiers?

Overloaded Methods may have different access modifiers. Methods from the superclass can also be overloaded in a subclass. Determining which overloaded Method will be invoked is decided at compile time on the basis of the reference type.

Can we override static method in Java?

Static methods are bonded at compile time using static binding. Therefore, we cannot override static methods in Java.

Can we override private method in Java?

No, we cannot override private or static methods in Java. Private methods in Java are not visible to any other class which limits their scope to the class in which they are declared.
