import java.util.*;

public class CountWordsInString {
    public static void main(String[] args) {
        String original = "I am rahul am i sunil so i can say am i";
        // making String type of array
        String[] originalSplit = original.split(" ");
        // if word has only one occurrence
        int count = 1;
        // LinkedHashMap will store the word as key and number of occurrence as
        // value
        Map wordMap = new LinkedHashMap();

        for (int i = 0; i < originalSplit.length - 1; i++) {
            for (int j = i + 1; j < originalSplit.length; j++) {
                if (originalSplit[i].equals(originalSplit[j])) {
                    // Increment in count, it will count how many time word
                    // occurred
                    count++;
                }
            }
            // if word is already present so we will not add in Map
            if (wordMap.containsKey(originalSplit[i])) {
                count = 1;
            } else {
                wordMap.put(originalSplit[i], count);
                count = 1;
            }
        }

        Set word = wordMap.entrySet();
        Iterator itr = word.iterator();
        while (itr.hasNext()) {
            Map.Entry map = (Map.Entry) itr.next();
            // Printing
            System.out.println(map.getKey() + " " + map.getValue());
        }
    }
}
