 Sample 1. Method to get a map of words and their count by passing in the string

Map<String,Integer> wordCountMap = new TreeMap();
String[] words = text.split(" ");
Set<Integer> countSet;
for(String word: words) {
if(wordCountMap.containsKey(word.toLowerCase())){
wordCountMap.put(word.toLowerCase(), wordCountMap.get(word.toLowerCase()).intValue() + 1);
} else {
wordCountMap.put(word.toLowerCase(), 1);
}
}

countSet = new TreeSet(Collections.reverseOrder());
countSet.addAll(wordCountMap.values());

for(Integer inte: countSet) {
for(Entry<String,Integer> entry: wordCountMap.entrySet()){
if(entry.getValue() == inte) {
System.out.println(entry);
}
}
}

 Sample 2. Sorting elements of a set using TreeSet

Set<String> mySet = new HashSet<String>();
mySet.add("D");
mySet.add("A");
mySet.add("B");
mySet.add("C");
mySet.add("E");

System.out.println(mySet); // May be Sorted but sorting is not guaranteed

mySet = new TreeSet<String>(mySet);

System.out.println(mySet); // Sorted
