To determine that a word is duplicate, we are mainitaining aHashSet. If theSet.add()method returnfalse, the it means that word is already present in the set and thus it is duplicate. List<String>wordsList=Arrays.stream(sentence.split(" ")).collect(Collectors.toList());Set<String>tempS...

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...
