Hi Friend,

Try the following code:

import java.util.*;
class Circle{
static double pi=3.14;
double radius;
Circle(){
}
Circle(double radius){
this.radius=radius;
}
public double getRadius(){
return radius;
}
public static Circle createCircle(){
System.out.println("Enter Radius");
Scanner input=new Scanner(System.in);
double r=input.nextDouble();
Circle c=new Circle(r);
return c;
}
public static void calculate(Circle c){
double r=c.getRadius();
double area=pi*r*r;
double circumference=2*pi*r;
System.out.println("Area: "+area);
System.out.println("Circumference: "+circumference);
}
public static void main(String[] args)
{

Circle c=createCircle();
calculate(c);
}
}import java.util.*;
class Circle{
static double pi=3.14;
double radius;
Circle(){
}
Circle(double radius){
this.radius=radius;
}
public double getRadius(){
return radius;
}
public static Circle createCircle(){
System.out.println("Enter Radius");
Scanner input=new Scanner(System.in);
double r=input.nextDouble();
Circle c=new Circle(r);
return c;
}
public static void calculate(Circle c){
double r=c.getRadius();
double area=pi*r*r;
double circumference=2*pi*r;
System.out.println("Area: "+area);
System.out.println("Circumference: "+circumference);
}
public static void main(String[] args)
{

Circle c=createCircle();
calculate(c);
}
}

Thanks
