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:...
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...
