Calculate the area of circle and cylinder by creating methods name area of circle and area of cylinder in a class named Area using a constant variable PI=3.14.

class Area
 {
     double pi=3.14;
     int r=Integer.parseInt(System.console().readLine("enter the value r"));
     int h=Integer.parseInt(System.console().readLine("enter the value h"));
     void areaOfCircle()
       {
         double area1=pi*r*r;
         System.out.println("area of circle="+area1);
       }
     void areaOfCylinder()
       {
         double area2=2*pi*r*(r+h);
         System.out.println("area of cylinder="+area2);
       }
   public static void main(String args[])
    {
         Area a=new Area();
         a.areaOfCircle();
         a.areaOfCylinder();
    }
}
