Why to use overriding in java?

Answer 1

Overriding is closely connected to polymorphism. Redefining method is similar to Overriding but you cannot expect those redefined methods to deliver polymorphism.

The concept of redefining is used when it involves static methods.

Answer 2

Overloading is when multiple methods are created with the same name but different arguments:

public static int max(int x,int y){...}

public static int max(double x,double y){...}

public static int max(float x,float y){...}

Overriding is when a subclass redefines a method previously defined in a parent class.

class A

{

public void foo(){System.out.println("Class A, method foo");}

}

class B extends A

{

public void foo(){System.out.println("Class B,method foo");}

}

Answer 3

• Overloading is when you have multiple methods of the same name,same parameter list,same return type in a single class.Among method name, parameter list ,return type any thing must be different.

• Overriding is when you have methods in a child class that has the same name,same parameter list,same return type as in the parent class.

Answer 4

Any time you have a class that inherits a method from a superclass, you have the opportunity to override the method (unless, the method is marked final). The key benefit of overriding is the ability to define behavior that's specific to a particular subclass type. The following example demonstrates a Porsche subclass of Car overriding the Car version of the drive() method:

public class Car {

public void drive() {

System.out.println("Generic Car Driving Generically");

}

}

class Porsche extends Car {

public void drive() {

System.out.println("Porsche driving Full Throttle");

}

}
