What is the Difference between Overriding and overloading?

Overloading 

All the method will share the same name but  it differes based on the parameter, type of parameter and  number of parameter  

overloading does not take return type to differentiate overloaded method.
ex: int add(int a, int b) int add(float a , float b) are overloaded methods

Overriding 

The method in the derived class the has the  same name in the base class and it changes the behaviour or  functionality of the method in the base class.

overriding comes with inheritance concept. here parent and child both contains the same method. and  when execution takes place; child's method is called.

overriding->     1) method should be public.     2)it need inheritance.     3)it need virtual keyword before it declartion.     4)it have same name with same parameter in diffrent   class.     5)it require non-static method.     6)method should have same datatype. Overloading->     1)method can be different access speicifier.     2)it doesn't need inheritacne.     3)all method should be in same class.     4)method can have diffrent datatypes

OVERLOADING:- 1) overloaded methods have the same name but  different parameter list. 2)a subclass method can overload a superclass method   eg:-int add(int a, int b) int add(float a , float b) are overloaded methods    OVERRIDING:- it just in inheritance  and the overriding method must hold the same name and the same signatures . the change maybe just in behavior .   The Cat class in the following example is the subclass and  the Animal class is the superclass. The Cat class overrides  eat() method inherited from Animal class.  public class Animal {      public void eat() {         System.out.println("Eat for Animal");     } }  public class Cat extends Animal {      public void eat() {         System.out.println("Eat for Cat");     } }
