       System.out.println("Enter the First Side");

       int a=Integer.parseInt(br.readLine());

       System.out.println("Enter the Second Side");

       int b=Integer.parseInt(br.readLine());

       System.out.println("Enter the Third Side");

       int c=Integer.parseInt(br.readLine());

       int s=(a+b+c)/2;

       int a1=(s*(s-a)*(s-b)*(s-c));

       double area=Math.sqrt(a1);

       System.out.println("The area of the triangle is = "+area);
