Overloading the same method name with different number of arguments (and the data types), and perhaps with a different returned data type. The method signatures are different, only the names are the same.

Overriding is to change the same method name with different implementation (the method body). The method signature stays the same.

Overriding - same method names with same arguments and same return types associated in a class and its subclass. Example: class CSuper { null print ( string _name)

{ print "Hello" + _name; } };

class CDerived { null print ( string _name)

{ print "Hello" + _name + "from Derived"; } };

Overloading - same method name with different arguments, may or may not be same return type written in the same class itself. Example: class CClass

{ string print( int i); string print(int i, char c); };

Overloading constructor means when you have multiple constructors in a class but with different number of arguments.

We cannot override a constructor, but we can override a method having same arguments and same return type. This means when I subclass a particular class then I can call the superclass's class method and override that with subclass's own logic.

Overloading is used when you want multiple methods with the same name and do similar things, with a small difference in the parameters being passed.

ex:

add(int a, int b);

add(float a, float b);

etc

Overriding is used when you want to mask/override some feature available in a parent class in the child class

Both are Java Polymorphism concepts

overriding means you're changing an already existing method.

overloading means you're using the same method name, but you use different parameters in each one.

What is the scope of method overloading and overriding?

Overloading happens when you have multiple methods in the current class that have the same name but different signature. The scope of method overloading is "Within the current class" Overriding happens when your current class extends another class (the parent class) and provides implementation for a method that is already available in the parent class. The scope of method overriding too is "Within the current class"

What is the difference between overloading and overriding methods in object?

Here are some of the most common differences between both of them. If you are working in Java for more than 1 year, you might be familiar with all of them but any way its good revision: 1) First and major difference between Overloading and Overriding is that former occur during compile time while later occur during runtime. 2) Second difference between Overloading and Overriding is that, you can overload method in same class but you can only override method in sub class. 3) Third difference is that you can overload static method in Java but you can not override static method in Java. In fact when you declare same method in Sub Class it's known as method hiding because it hide super class method instead of overriding it. 4) Overloaded methods are bonded using static binding and Type of reference variable is used, while Overridden method are bonded using dynamic bonding based upon actual Object. 5) Rules of Overloading and Overriding is different in Java. In order to overload a method you need to change its method signature but that is not required for overriding any method in Java.


Difference between Method overloading and method overriding in C plus plus?

Yes. Any base class method that is declared virtual can be overridden by a derived class. Overriding a method that is not declared virtual can still be called, but will not be called polymorphically. That is, if you call the base class method, the base class method will execute, not the override. To call a non-virtual override you must call it explicitly.


Why do you use of operator overloading in c?

Overloading, Overriding, Polymorphism, Information Hiding, Inheritance all these are CONCEPTS of C++ and Java. An Object Oriented Language and not of C language. Thats why Bjarne Stroustrup came up with C++ ...

How you compare and contrast overloading and overriding methods in java?

Method overloading is when you have multiple methods in a class that have the same name but a different signature. Method overriding is similar to method overloading, with a small difference. In overriding, a method in a parent class is overridden in the child class. The method in the child class will have the same signature as that of the parent class. Since the method in the child class has the same signature & name as the method of its parent class, it is termed as overriding. In situations where you may have to explicitly call the parent class method you can use the "super" keyword and for explicitly calling the current objects method you can use the "this" keyword.


What is method overriding and overloading in java?

Overloading is the means by which we can provide two or more different definitions of the same method in the same namespace. Overriding is the means by which a derived class may redefine the meaning of a base class method.

What is overloading and overriding in PHP?

Overcrowding of Functions: The same function has the same name in function overloading, but it does different things depending on how many arguments it has. For instance, if the radius is given, it should return the area of the circle; if the height and width are given, it should return the area of the rectangle, among other shapes. Function overloading cannot be accomplished using a native approach, as with other OOP languages. The magic function __call() is used to perform function overloading in PHP. Name and arguments for this function are accepted. Function overriding: Function overrides are similar to those used in other OOP programming languages. Function overriding should use the same name and number of arguments for both parent and child classes. In child classes, it takes the place of the parent method. Overriding is used to alter the parent class method's behavior. Overriding refers to two methods that share the same name and parameter. Visit now for more information- jai infoway


What is differnce between overloading and overriding?

Overloading is when you're asking something, usually some sort of machinery, to do more than it's designed to. Say you have an elevator that's rated for 5 people, but you cram more persons into it - then the elevator is overloaded. Overriding is when an operator decides to ignore or bypass a warning. Say that the warning light for low oil pressure/level lights up in a car, but the driver decides to keep going - then the driver is overriding the warning signal.
