import java.util.HashMap;

 

public class FinalCountWords {

 

    public static void main(String[] args) {

        String str = "I am Developer java java";

        String[] split = str.split(" ");

        HashMap<String,Integer> map = new HashMap<String,Integer>();

        for (int i=0; i<split.length-1; i++) {

        if (map.containsKey(split[i])) {

        int count = map.get(split[i]);

         map.put(split[i], count+1);

         }

         else

       {

         map.put(split[i], 1);

        }

        }

        System.out.println(map);

    }

 

}
