Here is an example of how System.arraycopy() can be used to remove an element from an array in Java: public class Main { public static void main(String[] args) { int[] arr = {1, 2, 3, 4, 5}; int removeIndex = 2; int[] newArr = new int[arr.length - 1]; System.array...
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...
System.out.print("Remove duplicate result: "); // // Create an array to convert the Set back to array. // The Set.toArray() method copy the value in the set to the // defined array. // String[] result =newString[set.size()]; set.toArray(result); for(String s : result) {...
2. UsingStream.distinct()to Remove Duplicate Elements and Get a New List We can use the Java 8Stream.distinct()method which returns a stream consisting of the distinct elements compared by the object’sequals()method. Finally, collect all district elements asListusingCollectors.toList(). ArrayL...
a[n-1] element is added to the res array. Finally, return the res array. Code Implementation C++ Java Python #include<bits/stdc++.h> using namespace std; void removeDuplicates(vector<int> a,int n){ vector<int> res; sort(a.begin(),a.end()); for(int i=0;i<n-1;i++){ if...
这道题跟remove duplicate sorted array是一样的。。。还是双指针,一个帮忙记录length外加替换不是elem的值,一个帮忙往前找。 代码如下: 1publicintremoveElement(int[] A,intelem) { 2if(A==null||A.length == 0) 3return0; 4 5intlen = 0; ...
