3. Find Duplicate Words usingCollections Largely, the process to find the duplicates using Collections is simlar to previous approach. We start with splitting the string and collecting all words in aList. Then we use theHashSet.add()method to check if the word is unique or duplicate. List<...

For parallel streams, relaxing the ordering constraint can sometimes enable more efficient execution. Certain aggregate operations, such as filtering duplicates (distinct()) or grouped reductions (Collectors.groupingBy()) can be implemented more efficiently if ordering of elements is not relevant. Similarl...
