Method overloading is when you have 2 or more methods in the same class with the same name but different parameters. Overriding is when the child class implements a method differently from its parent class.

Ali · Answer

Method Overloading is when a " method"  different forms. more precisely when two or more method have the same name but a different number of parameters and/or data types
For Example, take a  method name  "addNumber" can accept two int type parameter or two float type parameters.

addNumber(int a , int b) 
addNumber(float a, float b) 


Method Overriding is when a child class overrides the parent class method and implements its own instruction.  
Method Override requires inheritance while method loading happens in the same class.
