Let’s learn java program to calculate area of circle using method.

## Java program to calculate area of circle using method

To find area of a circle using method in java, first we have to write calculateArea() method which accepts radius as parameter to calculate area of circle in java.

Then in the next step, in main() method we have to call calculateArea() method.

Here’s the java program to calculate area of circle using method.

import java.util.Scanner; public class AreaOfCircleMethod { public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.println("Please enter radius : "); double radius = sc.nextDouble(); // area of circle in java double area = calculateArea(radius); System.out.println("Area of circle : " + area); sc.close(); } static double calculateArea(double r) { return (22 * r * r) / 7; } }

**Output:**

Please enter radius : 5

Area of circle : 78.57142857142857
