Count of duplicate elements:3Duplicate elements in the array:[1,3,5]Unique elements in the array:[2,4] 2. UsingStreamandSet Java Setclass stores only the distinct elements. We can use this feature to find the distinct elements in the array and then find unique and duplicate elements using...
In this tutorial, we’re going to explore the available options for handling aMapwith duplicate keys or, in other words, aMapthat allows storing multiple values for a single key. 2. Standard Maps Java has several implementations of the interfaceMap, each one with its own particularities. Howeve...

In this section, we’ll tackle the problem using the functionalities introduced in Java 8. 4.1. Using Stream withgroupingBy() ThegroupingBy()collector, which ships with the Stream API, allows us to group stream elements based on a classifier function, storing them as lists under corresponding ke...
We will print the elements present in the index range from i=0 to i=k-1 before returning the value of k, which is now the total number of unique elements in the array. Code Implementation C++ Java Python #include<bits/stdc++.h> using namespace std; int removeDuplicates(vector<int> ...
