Anagrams

 

Anagram is a type of word or phrase generating by rearranging the letters of a given word or phrase to produce a new word or phrase. Need to use all the original letters exactly once to frame new word or phrase. Some of the famous Anagram words are given below,
Anagrams

Debit cardBad credit
Eleven plus twoTwelve plus one
Payment receivedEvery cent paid me
AstronomerMoon starer
DormitoryDirty room
PunishmentNine Thumps
DesperationA rope ends it
Snooze alarmsAlas! No more Zs

and lot more are there...


Lets implement anagrams in java for only words to generate. 

public class Anagram {

 private HashSet<String> words = new HashSet<String>();
 
 public static void main(String[] args) throws Exception {
  
  String myWord = "art";

  Anagram obj = new Anagram();
  
  obj.getAnagramWords("", myWord);
  
  obj.printAnagramWords();
  
 }

 public void getAnagramWords(String prefix, String word) {
  if (word.length() <= 1) {
   words.add(prefix+word);
  } else {
   for (int i = 0; i < word.length(); i++) {
    String middle = word.substring(i, i + 1);
    String before = word.substring(0, i);
    String after = word.substring(i + 1);
    getAnagramWords(prefix + middle, before + after);
   }
  }  
 }
 
 public void printAnagramWords(){
  System.out.println("LIST OF ANAGRAM WORDS :::");
  for (String string : words) {
   System.out.println(string);   
  }
 }
}

OUTPUT:


LIST OF ANAGRAM WORDS :::
rta
atr
tra
art
