In the following code, the predicate adds the current element to aHashSet. As aHashSetdoes not allow duplicate items, theadd()method returnsfalsefor them. All such duplicate items are removed from theList, and finally, theListcontains only the unique items. List<Integer>items=newArrayList<>(...
Let’s look at a simple example of using distinct() to remove duplicate elements from alist. package com.journaldev.java; import java.util.ArrayList; import java.util.List; import java.util.stream.Collectors; public class JavaStreamDistinct { public static void main(String[] args) { List<Dat...
那么就应该 suppose 返回来的链表就已经没有重复项了,此时接到 head 结点后面,在第三句的时候再来检查一下 head 是否又 duplicate 了,实际上递归一直走到了末尾结点,再不断的回溯回来,进行删除重复结点,参见代码如下:
distinctElementsSet.removeAll(Arrays.asList(duplicateElementsArray));Integer[]uniqueElementsArray=distinctElementsSet.toArray(Integer[]::new);System.out.println("Unique elements in the array : "+Arrays.toString(uniqueElementsArray));//[2, 4] 3. Conclusion In this short Java tutorial, we learned ...
// the duplicate value will be removed. // List<String> list = Arrays.asList(data); Set<String> set =newHashSet<String>(list); System.out.print("Remove duplicate result: "); // // Create an array to convert the Set back to array. ...

As result I would like to get a list where ALL persons where the age is duplicate to be removed from the list. For this example "Barry" and "Kate" should not be included in the list.If something is not clear please, let me know....
