Finding repeated words on a string and counting the repetitions

Question

I need to find repeated words on a string, and then count how many times they were repeated. So basically, if the input string is this:

String s = \"House, House         


        

Answer 1

public class StringsCount{

    public static void main(String args[]) {

        String value = "This is testing Program testing Program";

        String item[] = value.split(" ");

        HashMap map = new HashMap<>();

        for (String t : item) {
            if (map.containsKey(t)) {
                map.put(t, map.get(t) + 1);

            } else {
                map.put(t, 1);
            }
        }
        Set keys = map.keySet();
        for (String key : keys) {
            System.out.println(key);
            System.out.println(map.get(key));
        }

    }
}
