String text = "one two one two three two four three";

String[] words = text.split(" ");

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

for (int i = 0; i < words.length; i++) {

int count = 0;

if (wordCount.containsKey(words[i])) {

count = wordCount.get(words[i]);

}

wordCount.put(words[i], count + 1);

System.out.println(words[i] + ": " + count);
