    Java is as easy :

    public static boolean isPangram(String s) {
        s = s.toLowerCase();
        s = s.replaceAll("\\s", "");
        
        SortedSet<Character> set = s.chars()
                .mapToObj(c -> (char) c)
                .collect(Collectors.toCollection(TreeSet:: new));
        
        return set.size() == 26;
    }
