    ****Java logic for initializing a static block

      static  int B;
  static  int H;
       static  Scanner scan =  new Scanner(System.in);

    static{
        B  = scan.nextInt();
        H = scan.nextInt();
				scan.close();
        if(B>0 && H>0)
        {
            System.out.println(B*H);
            
        }
        else{
            System.out.println("java.lang.Exception: Breadth and height must be positive");
        }
    }
