BufferReader Class in Java

  InputStreamReader is = new InputStreamReader(System.in);

        BufferedReader bf = new BufferedReader(is);

        System.out.print("Enter a value : ");

        String s = bf.readLine();

        int n = Integer.parseInt(bf.readLine());

        System.out.println(s);

        System.out.println(n);

OR

 BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

        System.out.println("Enter a value");

        String s = br.readLine();

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