Write a program to calculate area and perimeter of a circle in Java.

Here is the code of the program:

import java.io.*;
class RecArea
{
public static void main(String[] args)
{

 int l=0;
 int w=0;

 try{

   BufferedReader br1 = new BufferedReader(new InputStreamReader(System.in));
   System.out.println("Enter length of rectangle : ");
   l = Integer.parseInt(br1.readLine());
   System.out.println("Enter width of rectangle : ");
   w = Integer.parseInt(br1.readLine());
   int area = l*w;
   System.out.println("Area of Rectangle : "+area);
   int perimiter = 2*(l+w);
   System.out.println("Perimeter: " + perimiter);

 }catch(Exception e){System.out.println("Error : "+e);}

}
}
