Why is method overloading not possible by changing the return type in Java?

Can we change the return type in method overloading in Java?

Method overloading cannot be done by changing the return type of methods. The most important rule of method overloading is that two overloaded methods must have different parameters.

Can we do method overloading by changing the 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).

Why function overloading does not depend on the return type?

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.

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.

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. Static methods can be overloaded (meaning that you can have the same method name for several methods as long as they have different parameter types).

Can we override private method in Java?

1) In Java, inner Class is allowed to access private data members of outer class. … 2) In Java, methods declared as private can never be overridden, they are in-fact bounded during compile time.

Can constructor be overloaded?

Yes! Java supports constructor overloading. In constructor loading, we create multiple constructors with the same name but with different parameters types or with different no of parameters.

Is overriding possible in Java?

In Java, methods are virtual by default. We can have multilevel method-overriding. Overriding vs Overloading : … Overriding is about same method, same signature but different classes connected through inheritance.

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).

Is return type considered in function overloading?

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.

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() { ... }

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.
