the base class method is overridden by the derived class. Java doesn’t support method overloading by changing the return type of the function only as it leads to ambiguity at compile time.

In conclusion, the class gives its own specific implementation to an inherited method without even modifying the parent class. right? Feel free to comment your question below. Basically, the method to execute is chosen on the basis of the type of object and not on the type of reference variable. All Rights Reserved. Note that a data type can be promoted but not demoted to a lesser type implicitly. home and car and using it. But you must have to … The class Circle will override the method of interface and implement it.

When we don’t want the method to be overridden, we declare it as final.

Suppose that we have a class operation to multiply numbers (two or more, float or int) and the class contains the new method for every kind of multiplication we perform.

Hi Kiran,

Method Overloading in Java is an aspect of a class to include more than one method with the same name but vary in their parameter lists. Similarly, char can be promoted to int, long, float, double and so forth. Java constructor cannot be the same for a parent class and a subclass because it must always be the same as the class name.
