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.

Overriding is a feature in Java where you can override (mask) the features of the parent class in the child class.

Lets say you have a method printName() in the parent class which prints the name of that class. When you extend this class in a child class if you call the method printName() the name of the parent would be displayed. Which you may want to change. If you want to display only the name of the child class then you can write the method printName() in the child class. On invocation the name of the child class would be printed.

Tip: If you want to display the name of the parent class somewhere you can invoke it by using super.printName() because once you override that method in the child class you cannot access the parent class method directly.

Overriding is a coding methodology where you code a method in the child class which is already defined in the parent class.

ex:

public class A {

public String getName(){

...

}

}

public class B extends A {

public String getName(){

...

}

}

The method getName() is overridden in Class B because it is already defined in Class A.

Is overriding a dynamic polymorphism in c plus plus or not?

In C++, overriding and function, method, or operator is a different thing than (dynamic) polymorphism, so overriding a polymorphic method is almost entirely possible.


Example of overriding in java?

For example: class Speak { void SayHello(){}; } class Boy extends Speak { void SayHello(){System.out.println("I'm a boy");} } So overriding is usual to rewrite the motheds in subclasses .In subclsses ,you can override the methods acceded from his parent 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.

What is a operator overriding in java?

Java does not support object overriding. It does support operator overloading by means of the "+" symbol which is used for both numeric addition as well as string concatenation.


Why use function overriding in Java?

You use function overriding in Java when you inherit a bunch of features from a class and for a few particular cases alone, you do not wish to use the functionality of the parent class and wish to implement a custom feature in your class. In such cases, you create a method in your class with the same name and signature as in your parent class, thereby overloading it. this way only your current class will be used by the JVM unless specifically invoked by using the super keyword.

When the concept of method overriding is necessary?

concept of overriding is very important as due to overriding the derived class can use the function of the base class! when the function has same name and prototype in both the classes(base and derived) then the derived class can use the funtion of base class!


What is function in java terminology?

In Java, a function is called a "method". In Java as well as other languages, a method is a function defined specifically for one class. In Java, this is the only way to define functions, therefore, all functions are methods.In Java, a function is called a "method".

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.
