In this tutorial you will learn the method of calculating the area of circle. In this program you will be taught each and every steps that have used in this program. The description of this program is given below.
Description of program:
In this section we will learn how to use of static method. First of all, we have to define class name "StaticCircle" then define further instance variable in the class. After that we must declare method class which take the double type value by using the "this.radius" operator. Now we will have to declare the type double, which take the defined value of radius and pi-value. Then we have to create object and call the area of circle. After that it return the area of circle, return the doubles type values. Thus output will be display on the screen by using the println() method.
The code is given below
