Quick Answer: Is Overloading Possible In Inheritance?

Can we overload method in different class?

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

It is a valid question since usually, overloading is explained using two methods with the same name (but different parameters) in the same class..

Which type of inheritance Cannot involve private inheritance?

Which type of inheritance cannot involve private inheritance? Explanation: This is a common type of inheritance where the protected and public members of parent class become private members in child class. There is no type which doesn’t support private inheritance.

Can be achieved through inheritance?

Multiple Inheritance (Through Interfaces) : In Multiple inheritance ,one class can have more than one superclass and inherit features from all parent classes. Please note that Java does not support multiple inheritance with classes. In java, we can achieve multiple inheritance only through Interfaces.

When a method overloading what happens?

Method Overloading is a feature that allows a class to have more than one method having the same name, if their argument lists are different. It is similar to constructor overloading in Java, that allows a class to have more than one constructor having different argument lists.

Can overridden method be overloaded?

You can overload the method as long as its signature is unique within the class, the base class is not considered. The reason nothing is printed is because in the overloaded method you are just returning the passed in value rather than printing it.

What is overloading in oops?

A major topic in OOP is overloading methods, which lets you define the same method multiple times so that you can call them with different argument lists (a method’s argument list is called its signature). … You can call Area with either one or two arguments.

What is overloading and overriding?

Overloading occurs when two or more methods in one class have the same method name but different parameters. Overriding occurs when two methods have the same method name and parameters. One of the methods is in the parent class, and the other is in the child class.

Can overloading happen in subclass?

Usually, method overloading happens inside a single class, but a method can also be treated as overloaded in the subclass of that class — because the subclass inherits one version of the method from the parent class and then can have another overloaded version in its class definition.

How does overloading differ with and without inheritance?

Abstract. Overloading allows several function definitions for the same name, distinguished primarily through different argument types; it is typically resolved at compile-time. Inheritance allows subclasses to define more special versions of the same function; it is typically resolved at run-time.

Why is overloading needed?

Overloading in Java is the ability tocreate multiple methods of the same name, but with different parameters. … Overloaded methods give programmers theflexibility to call a similar method for different types of data. Overloading is also used on constructors to create new objects givendifferent amounts of data.

What is difference between method overloading and method overriding?

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.

How method overloading takes place?

Two or more methods can have same name inside the same class if they accept different arguments. This feature is known as method overloading. Method overloading is achieved by either: changing the number of arguments.

Can constructors 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.

What is multiple inheritance example?

Multiple Inheritance is a feature of C++ where a class can inherit from more than one classes. The constructors of inherited classes are called in the same order in which they are inherited. For example, in the following program, B’s constructor is called before A’s constructor.

What are types of inheritance?

Different Types of InheritanceSingle inheritance.Multi-level inheritance.Multiple inheritance.Multipath inheritance.Hierarchical Inheritance.Hybrid Inheritance.

What is overloading when does it occur?

When the current in the circuit exceeds, the load exceeds the specified limit and overloading occurs. If many electrical appliances of high power ratings such as geyser, iron, air conditioner, etc, are switched on simultaneously overloading may occur.

Why overloading is called compile time polymorphism?

In overloading, the method / function has a same name but different signatures. It is also known as Compile Time Polymorphism because the decision of which method is to be called is made at compile time. Overloading is the concept in which method names are the same with a different set of parameters.

Can overloading be done with different return types?

No, you cannot overload a method based on different return type but same argument type and number in java. same name. different parameters (different type or, different number or both).
