Java Example Code

With the help of given Java code you can return the area of a circle and give the radius as a parameter.

import java.io.*;

public class AreaAndParameter
{
public static void main(String[] args)
{
double r=0;
try{
BufferedReader br1 = new BufferedReader(new InputStreamReader(System.in));
System.out.print("Enter Radius of Circle : ");
r = Integer.parseInt(br1.readLine());
AreaAndParameter a = new AreaAndParameter();
double area = a.areaOfCircle(r);
System.out.println("Area of Circle : "+area);
double perimeter = a.perimeterOfCircle(r);
System.out.println("Perimeter of Circle : "+perimeter);

}
catch(Exception e){

System.out.println("Error : "+e);
}
}
public double areaOfCircle(double r){
double area = Math.PI*r*r;
return area;
}
public double perimeterOfCircle(double r){
double perimeter = 2*Math.PI*r;
return perimeter; }}
