import java.util.Scanner;

public class RectInfo {

  public static void main(String [] args){

     Scanner sc = new Scanner(System.in);

     double length = sc.nextDouble();

     double breadth = sc.nextDouble();

     System.out.println("Area of the rectangle is - " + length * breadth);

     System.out.println("Perimeter of the rectangle is - " + 2 * (length + breadth));

  }

}

• We imported Scanner class for taking input from the user.
• We declared class name as "RectInfo".
• Then there is main method.
• We activated the scanner.
• We took input in two variables as length and breadth respectively.
• We printed them using the println() method.
• And finished it...

Hope it helps...
