public Map getWordsWithCount(String sentances)
{
    Map wordsWithCount = new HashMap();

    String[] words = sentances.split(" ");
    for (String word : words)
    {
        if(wordsWithCount.containsKey(word))
        {
            wordsWithCount.put(word, wordsWithCount.get(word)+1);
        }
        else
        {
            wordsWithCount.put(word, 1);
        }

    }

    return wordsWithCount;

}
