No, you cannot overload a method based on different return type but same argument type and number in java. same name.
Can we override method which have different return type with same name and signature?
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.
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 overloaded functions have different return types Java?
Overloaded methods in java may have different return types given that the argument is also different. Check out the sample code. The compiler does not consider return type when differentiating methods, so you cannot declare two methods with the same signature even if they have a different return type.Do overloaded methods have the same signature?
Method overloading happens with methods with the same name but different signature. Method overriding happens with methods with the same name and same signature between inherited classes.
Is it possible to have different return types for a overloaded method?
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.
Can we overload method with different 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 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.Can we have same method with different return type?
We can not define more than one method with the same name, Order, and type of the arguments. 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.
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 onWhat is the difference between override and overload?
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.
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.
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).
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.
When a method having the same name as that the name of the class where it is defined?
A constructor is a method that initializes an object immediately upon creation. It has the same name as that of class in which it resides.
When a method has the same name and takes different numbers and or types of parameters as a method in the same class?
Overloading occurs when two or more methods in one class have the same method name but different parameters.
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.
What are override methods?
An override method provides a new implementation of the method inherited from a base class. The method that is overridden by an override declaration is known as the overridden base method. An override method must have the same signature as the overridden base method. … You cannot override a non-virtual or static method.
Can we override static method?
Static methods cannot be overridden because they are not dispatched on the object instance at runtime. The compiler decides which method gets called.
Can we have different return type in method overriding in C#?
You cannot change the return type of method during overriding.
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 overload 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 in method overriding methods Cannot have less visibility?
Answer: Overriding methods must have the same name, parameter list, and same return type. i.e., they must have the exact signature of the method we are going to override, including return type. The overriding method cannot be less visible than the method it overrides.
What is the difference between override and overwrite?
To “overwrite” something is to put something else in its place, destroying the thing overwritten. To “override” something is to cause something else to operate instead of it without harming or changing the thing overridden.
What is method overloading and overriding?
Method OverloadingMethod OverridingIt is used to increase the readability of the programProvides a specific implementation of the method already in the parent classIt is performed within the same classIt involves multiple classes
What is the difference between override and overload in C#?
Key Difference – Overriding vs Overloading in C# The key difference between overriding and overloading in C# is that the binding of overridden method call to its definition happens at runtime while the binding of overloaded method call to its definition happens at compile time.
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.
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).
When you overload a method you write multiple methods with the same?
Overloading happens when you have two methods with the same name but different signatures (or arguments). In a class we can implement two or more methods with the same name. Overloaded methods are differentiated based on the number and type of parameter passed as arguments to the methods.
Can we have two methods in a class with the same name?
Yes, we can define multiple methods in a class with the same name but with different types of parameters. … Depending on the parameters, the appropriate method will be called.
Can a overriding method throw new or broader checked exception?
An overriding method can throw any unchecked exceptions, regardless of whether the overridden method throws exceptions or not. However, the overriding method should not throw checked exceptions that are new or broader than the ones declared by the overridden method.
