What is the difference between method overriding and method overloading?

Question

Accepted Answer

Method overriding involves creating a new implementation of a method in a subclass, while method overloading involves creating multiple methods with the same name but different parameters in the same class.

Method overriding is used to provide a specific implementation of a method that is already provided by its superclass.
Method overloading is used to create multiple methods with the same name but different parameters within the same class.
In method overriding, the method signature must be the same in both the superclass and subclass.
In method overloading, the method signature must be different, typically in terms of the number or type of parameters.
Example of method overriding: public class Animal { public void sound() { System.out.println("Animal makes a sound"); } } public class Dog extends Animal { public void sound() { System.out.println("Dog barks"); } }
Example of method overloading: public class Calculator { public int add(int a, int b) { return a + b; } public double add(double a, double b) { return a + b; } }
