Differentiate between overloading and overriding.

Question

Ashutosh Kumar Verma · Answer

Difference between Overloading and overriding- Overloading Overriding In case of method overloading there are two or more methods with same name in single class. In Overriding all methods have also same name but in different classes. There are different parameters passes in all same name methods. There are same parameter passes in all methods. In method overloading we can call all methods by a single instance of a class Here all methods can call with different class instance. It is call automatically suitable methods by passing argument. In method overriding all parameters are same so we need to call them with different class instance. Here all parameters are different in sequence, in types or in number of parameters. Here all parameters are same in sequence ,in types and in number of parameters.
