If we are interested in finding the duplicate words along with their count of occureneces in theString, we can use theCollections.frequency(list, item)API that counts the number of times aitemappears in the specifiedlist. Map<String,Integer>dupWordsMapWithCount=newHashMap<>();for(Stringword:...
); printDuplicateCharacters("Java"); } /* * Find all duplicate characters in a String and print each of them.*/ public static void printDuplicateCharacters(String word) { char[] characters = word.toCharArray(); // build HashMap with character and number of times they appear in String...
We can also find the duplicate characters and their count of occurrences in this string. Map<Character,Integer>duplicateCharsWithCount=bag.entrySet().stream().filter(e->bag.get(e.getKey())>1).collect(Collectors.toMap(p->p.getKey(),p->p.getValue()));System.out.println(duplicateCharsWithCo...
