We can combine the improved speed of the HashSet above with the speed and efficiency of a Java Stream to create a very succinct mechanism. That is how the code below removes duplicates from the Java List: List<Object> myList = List.of(0, 1, 1, 2, 3, 5, 6, 0, 0, 1, 5); H...
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<String>wordsList=Arrays.asList(sentence.s...
