Iterate overListusingStreamand find duplicate words 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(" "...
, Collectors.counting()))// create a map {1=1, 2=1, 3=2, 4=2, 5=1, 7=1, 9=2}.entrySet().stream()// Map -> Stream.filter(m -> m.getValue() >1)// if map value > 1, duplicate element.map(Map.Entry::getKey) .collect(Collectors.toSet()); } }Copy Output 3 4 9C...
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...
To find duplicate files, given input of String array is quite easy. Loop through each String and keep a HashMap of Strings to Set/Collection of Strings: mapping the contents of each file to a set of paths with filename concatenated. For me, instead of given a list of paths, I was gi...
