Can we override return type method?

Covariant return type works only for non-primitive return types. From Java 5 onwards, we can override a method by changing its return type only by abiding the condition that return type is a subclass of that of overridden method return type.

Can we override return type method in Java?

Before Java5, it was not possible to override any method by changing the return type. But now, since Java5, it is possible to override method by changing the return type if subclass overrides any method whose return type is Non-Primitive but it changes its return type to subclass type.

Can we change return type in method overriding and overloading?

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 change return type in method overriding in C++?

When overriding a method it is possible to change the return type as long as this change does not conflict (the type is covariant) with the declared method. This does not break the polymorphism as the covariant type of the override is also valid type for the method declaration.

Does return type matter in function overriding?

A subclass' overriding method should match its superclass or subclass' return type if the overriding method returns the same type. Underlining methods in subclasses should not override methods in the parent class and vice versa. A developer can only use the covariant return type for object types, not primitive ones.

Can we override a method by using same method name and arguments but different return types in Java?

Why return type is not considered in function overloading?

The function signature is examined during compilation. If the signatures aren't the same, functions can be overloaded. Function overloading is unaffected by a function's return type. Therefore, the same function signature with a different return type will not be overloaded.

Does a method always need a return type?

Every method in Java is declared with a return type and it is mandatory for all java methods. A return type may be a primitive type like int, float, double, a reference type or void type(returns nothing).

Can we overload return type in 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 is method overriding not possible by changing the return type in Java?

Q) Why Method Overloading is 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 I use return for a method of the return type void?

Within the body of the method, you use the return statement to return the value. Any method declared void doesn't return a value.

Can we override method without super keyword?

A method declared static cannot be overridden but can be re-declared. If a method cannot be inherited, then it cannot be overridden. A subclass within the same package as the instance's superclass can override any superclass method that is not declared private or final.

Can we override static method?

Static methods cannot be overridden since they are bonded at compile time and method overriding relies on dynamic binding at runtime.

Is return type considered in overloading?

The return type of a function does not create any effect on function overloading. Same function signature with different return type will not be overloaded.

Can we override string class?

No. String is final and therefore cannot be extended.

Can private and final methods be overloaded?

Yes, we can overload private methods in Java but, you can access these from the same class.

Is @override mandatory in Java?

While it is not required to use this annotation when overriding a method, it helps to prevent errors. If a method marked with @Override fails to correctly override a method in one of its superclasses, the compiler generates an error.

Can we overload main method?

The short answer to, can we overload main method in Java is Yes, we can overload the main() method in Java. A Java class can have any number of overloaded main() methods. But the very first thing JVM (Java Virtual Machine) seeks is the original main() method, i.e., public static void main(String[] args) to execute.

Can we overload final method in Java?

yes overloading final method is possible in java.As final methods are restricted not to override the methods. while overloading argument list must be different type of the overloading method.

Can we inherit static method in Java?

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.

What is difference between overloading and overriding?

When the method signature (name and parameters) are the same in the superclass and the child class, it's called overriding. When two or more methods in the same class have the same name but different parameters, it's called overloading.

Can you return twice in C++?

You can't, it is only possible once.

Can we achieve overloading in child class?

Overloading can happen in same class as well as parent-child class relationship whereas overriding happens only in an inheritance relationship.

Can a method have two return types?

Your answer

No, you don't have two return types.

Do static methods have a return type?

it is a static method (static), it does not return any result (return type is void), and. it has a parameter of type array of strings (see Unit 7).

How many return types can a method have?

A method can return at most one value. The method signature specifies the return type, which can be a primitive (int, double, boolean), a class (String, Turtle, etc), or void.
