Can we change return type in method overloading?

No, you cannot overload a method based on different return type but same argument type and number in java.

Does return type matter in method overloading?

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.

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

In java, method overloading is not possible by changing the return type of the method only because of ambiguity.

Can we overload method with different return type C++?

Function Overloading and Return Type in C++

Function overloading is possible in C++ and Java but only if the functions must differ from each other by the types and the number of arguments in the argument list. However, functions can not be overloaded if they differ only in the return type.

Why we Cannot overload function on the basis of 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.

Java Overloading methods (Different return types) | Java Tutorial

Can we override static method?

Overloading is the mechanism of binding the method call with the method body dynamically based on the parameters passed to the method call. Static methods are bonded at compile time using static binding. Therefore, we cannot override static methods in Java.

Can return type be different in method overriding?

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.

Why return type is not in function overloading in Java?

As said in previous answers, java does not support method overloading with different return type and same arguments. This is because, it has to determine which method to use at the compile time itself. To remove the ambiguity, they designed the method overloading technique like this.

Can we override private method in Java?

No, we cannot override private or static methods in Java. Private methods in Java are not visible to any other class which limits their scope to the class in which they are declared.

Which is incorrect about method overloading?

4. Which is incorrect statement regarding overloading? Return type is not considered in overloading.

Can you override a method with different parameters?

Both methods will still exist, so it's called overloading. In Java and in C Sharp it works pretty much the same; you just define a new method with different parameters. You cannot just change the return type, though. The parameters to the methods must be different in order to overload one.

Can private class be inherited?

Members of a class that are declared private are not inherited by subclasses of that class. Only members of a class that are declared protected or public are inherited by subclasses declared in a package other than the one in which the class is declared. The answer is No. They do not.

Can static method be private?

Static methods can be public or private. The static keyword is placed right after the public/private modifier and right before the type of variables and methods in their declarations.

Can abstract method override?

An abstract method is a method that is declared, but contains no implementation. you can override both abstract and normal methods inside an abstract class. only methods declared as final cannot be overridden.

Why method overloading is not possible by changing the return type of method only explain with proper Java programming example?

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.

Can we throw exception in overridden method?

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.

Can virtual function have different return type?

Yes. The return types are allowed to be different as long as they are covariant.

Can we change return type of main () method in Java?

We can change the return type for main method but java compiler will refuse to acknowledge it as entry point for our application.

Can we execute a class without a main method?

Yes, we can execute a java program without a main method by using a static block. Static block in Java is a group of statements that gets executed only once when the class is loaded into the memory by Java ClassLoader, It is also known as a static initialization block.

Can we override final method?

Any method that is declared as final in the superclass cannot be overridden by a subclass.

Can we inherit static class in Java?

Static methods do not use any instance variables of any object of the class they are defined in. Static methods take all the data from parameters and compute something from those parameters, with no reference to variables. We can inherit static methods in Java.

Can abstract method be private?

If a method of a class is private, you cannot access it outside the current class, not even from the child classes of it. But, incase of an abstract method, you cannot use it from the same class, you need to override it from subclass and use. Therefore, the abstract method cannot be private.

Can constructor be private?

Yes, we can declare a constructor as private. If we declare a constructor as private we are not able to create an object of a class. We can use this private constructor in the Singleton Design Pattern.

Can static variable be changed?

A static variable is common for all instances of the class. A final variable can not change after it has been set the first time. So a static final variable in Java is common for all instances of the class, and it can not be changed after it has been set the first time.

Can we achieve abstraction without encapsulation?

The object is the abstract form of the real-world and its details are hidden using encapsulation. Thus encapsulation is required for abstraction.
