In our method overloading example, for achieving consistency, we have used the same method name minFunction() to find the minimum of two different types of numbers, that is, int and double types. For each shape, we need 3 things: a (inner) class that holds the values that define the shape; a function that delivers an object of that class; and (crucially) an area() method that accepts a single argument, an object of the inner class. In this case, methods are said to be overloaded and this process is referred to as method overloading in java. Below are the topics you learn in the website. In this program, You will learn how to find the area of a circle using class and object in C++. The other problem with the base class is the use of two different methods. 2 Write a program to check the font class method as follows: Create a font TimesRoman bold and Italic size 12. A method "area" is created to calculate the area of the given rectangle, which basically multiplies the length and breadth of the rectangle. Interface provides a contract for all the implementation classes, so its good to code in terms of interfaces because implementation classes can't remove the methods we are using. Index value should be an integer.
