How To Count Occurrences Of Each Character In String In Java 8(lambda exp or streams) but not in traditional method?

Question

Sample output All Is Well : { =2, A=1, s=1, e=1, W=1, I=1, l=4}

I know how to do it in normal way like using map but using lambda or streams (java-8) I don't have idea — JAVA LOVER, Jan 24 '22 at 14:26

You may try this,

    Arrays.stream("inputstring".split(""))
            .map(String::toLowerCase)
            .collect(Collectors.groupingBy(s -> s, LinkedHashMap::new, Collectors.counting()))
            .forEach((k, v) -> System.out.println(k + " = " + v));
