Write a program for calculating area and perimeter of a rectangle

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);}

}
}
