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

## Java program to calculate area of circle using method

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

Also read – string toUpperCase() method 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,

// java area of a circle 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
