No, you cannot overload a method based on different return type but same argument type and number in java. … different parameters (different type or, different number or both).

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 happened if two methods have same name same parameters but different return types?

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. If both methods have the same parameter types, but different return types, then it is not possible.

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.

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.

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 the overloaded methods have the same return type?

No, you cannot overload a method based on different return type but same argument type and number in java. … different parameters (different type or, different number or both).

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 return type is not in function 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 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.

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

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.

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 overriding have different return types?

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.

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).

What are the different ways a method can be overloaded?

• 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 we have different 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.

Can you define two methods that have same name but different parameter types?

Method overloading. … The practice of defining two or more methods within the same class that share the same name but have different parameters is called overloading methods.

How can I overload a method in C#?

1. By changing number of parameters in a method.
2. By changing the order of parameters in a method.
3. By using different data types for parameters.

How is method overriding different from method overloading in C#?

Overloading is when you have multiple methods in the same scope, with the same name but different signatures. Overriding is a principle that allows you to change the functionality of a method in a child class.

How methods are overloaded in C sharp?

Two or more than two methods having the same name but different parameters is what we call method overloading in C#. Method overloading in C# can be performed by changing the number of arguments and the data type of the arguments.

Can you have two methods with the same name in Java?

For convenience, Java allows you to write more than one method in the same class definition with the same name. … Having two or more methods named the same in the same class is called overloading. It’s not overloading if you have the same method name in two different classes.

Which function Cannot overload?

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. For example, following program fails in compilation. 3) Parameter declarations that differ only in a pointer * versus an array [] are equivalent.

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.

What kinds of argument variations are allowed in method overloading?

Method Overloading allows two methods with same name to differ in: Number of parameters. Data type of parameters. Sequence of data type of parameters.

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.

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.

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.
