Scanner Class And String Buffer

Whenever I use Scanner class for input it shows a warning regarding memory leak, ".in" not closed. While using Buffered Reader it does not show any warning. Why So?

    class Demo    
    {    
        public static void main(String[] arg){    
        System.out.println("Enter a String");    
        Scanner sc = new Scanner(System.in);    
        String[] str = new String[1];    
        str[0] = sc.next();    
        System.out.println(str[0]);    
    }

In either case, you should close the Scanner or BufferedReader to avoid resource leaks. The compiler apparently doesn't recognize the problem with BufferedReader and doesn't issue the warning.
