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 type. It will throw a compile-time error.
Can we overload method with different return type 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. … Same function signature with different return type will not be overloaded.
Can the overloaded methods have the same return type?
No method overloading is not possible in case of different return type, because compiler can’t figure that which method he need to call.. In this case compiler will never know which method to be invoked. As long as you don’t do something like this: This is not valid for overloading.
Does function overloading depend on 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.Can a method be override with the same method name and arguments but different return types?
Yes. It is possible for overridden methods to have different return type . But the limitations are that the overridden method must have a return type that is more specific type of the return type of the actual method.
Can overloaded methods have different access modifiers?
Using the same method name but with different arguments is called overloading. … Overloaded Methods may have different access modifiers. Overloaded Methods may throw different exception broader or narrow no restriction. Methods from the superclass can also be overloaded in a subclass.
Can we have different return type in method overriding in C#?
You cannot change the return type of method during overriding.
Why methods are not overloaded based on return type?
This means that method overloading has no relation with return-type. In this way, we can define more than one Methods of the same name in a class called Method Overloading. The Java Compiler itself, based on the Data Type of the Arguments of the Methods, performs the appropriate method call for an object.Should return type be same in method overloading and overriding?
Return type of method does not matter in case of method overloading, it can be same or different. However in case of method overriding the overriding method can have more specific return type (refer this). Argument list should be different while doing method overloading.
Why method overloading is not possible by changing return type of method?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.
Article first time published onWhy we Cannot overload function on 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.
When you overload Java methods the methods are called using different arguments?
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.
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 three can vary in overloaded methods?
As discussed in the beginning of this guide, method overloading is done by declaring same method with different parameters. The parameters must be different in either of these: number, sequence or types of parameters (or arguments).
How do you overload a method?
- By changing the number of parameters in a method.
- By changing the order of parameters in a method.
- By using different data types for parameters.
Can you define two methods that have same name but different parameter types?
Overloading occurs when two or more methods in one class have the same method name but different parameters. … If the number of parameters is the same, then it must have different types of parameters. Overloading is known as compile-time polymorphism.
How can I overload a method in C#?
- By changing number of parameters in a method.
- By changing the order of parameters in a method.
- By using different data types for parameters.
Why return type is not in method overloading in C#?
Return type of functions is not a part of the mangled name which is generated by the compiler for uniquely identifying each function in the case of function overloading. are the parameters which are used to generate the unique mangled name for each function.
Can overloaded methods have different return types Java?
No, you cannot overload a method based on different return type but same argument type and number in java.
Can we override the overloaded method?
So can you override an overloaded function? Yes, since the overloaded method is a completely different method in the eyes of the compiler.
Can you overload the main method?
Yes, We can overload the main method in java but JVM only calls the original main method, it will never call our overloaded main method.
Why return type is not a part of method signature?
Return types and thrown exceptions are not considered to be a part of the method signature, nor are the names of parameters; they are ignored by the compiler for checking method uniqueness. The method signatures help distinguish overloaded methods (methods with the same name) in a class.
Which methods Cannot be overloaded in Java?
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 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.
When you overload a Java method you write multiple methods with a shared name?
When you overload a Java method, you write multiple methods with a shared name. When you write your own constructors, you cannot write versions that receive parameters. Fields declared to be static are not always final. An alternative to importing a class is to import an entire package of classes.
What feature allows different methods to have the same name and argument type but a different implementation is called?
Two or more method having same name but different argument in same class is known as overloading.
