Can we change return type in method overloading in Java?

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

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.

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.

Does overloading depends 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 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).

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 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.

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.

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() { ... }

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.

Should the return type of methods be same in overloading?

No method overloading is not possible in case of different return type, because compiler can’t figure that which method he need to call..

Can main method be overloaded?

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. Output: … So, to execute overloaded methods of main, we must call them from the original main method.

What is meant by method overloading?

Method overloading allows a class to define multiple methods with the same name, but different signatures. That is, it allows you to define different methods that have the same name, but that respond to correspondingly different messages sent to an instance of the class.
