    Here is my way, hope it could help someone

    		String smallest = s.substring(0, k);
        String largest = s.substring(2, 5);
        
        // Complete the function
        // 'smallest' must be the lexicographically smallest substring of length 'k'
        // 'largest' must be the lexicographically largest substring of length 'k'
        for ( int i = 0; i < s.length() - k + 1; i++) {
            if ( s.substring(i, i + k).compareTo(smallest) < 0) {
                smallest = s.substring(i, i + k);
            } else if ( s.substring(i, i + k).compareTo(largest) > 0 ) {
                largest = s.substring(i, i + k);
            }
        }
