Vaak moeten we een array klonen om een ​​back-up te maken van de originele elementen ervan. We hebben een aantal speciale strings en getallen, zoals palindroomnummer, palindroomstring en Armstrong-nummer, en om hun specialiteit te controleren, moeten we de array klonen. Om bijvoorbeeld te controleren of een string een palindroom is of niet, converteren we eerst een string naar een karakterarray en klonen we de char-array als een temp. Nu keren we de elementen van de char-array om en vergelijken deze met de temp die de originele string bevat.

In eenvoudige woorden: we moeten de array klonen als we een back-up van de originele gegevens willen maken. In Java hebben we vier manieren om een ​​array te klonen:

Door array-elementen te kopiëren

Het is de naïeve manier om een ​​array te klonen. Bij deze methode herhalen we de oorspronkelijke array en plaatsen we elk element van de array in een andere array. We klonen de array door elementen op de volgende manier te kopiëren:

CloneArrayExample1.java

 // import required classes and packages if any import java.util.Scanner; // create class CloneArrayExample1 to clone an array public class CloneArrayExample1 { // main() method start public static void main(String[] args) { // declare originalArray and cloneArray variables int originalArray[]; int cloneArray[]; int size; // create Scanner class object to take input from user Scanner sc = new Scanner(System.in); System.out.println(&apos;Enter the size of the array.&apos;); size = sc.nextInt(); // initialize both the array with the given size originalArray = new int[size]; cloneArray = new int[size]; System.out.println(&apos;Enter elements of the original array:&apos;); //take input from user to fill originalArray for(int i = 0; i <size; i++) { originalarray[i]="sc.nextInt();" } close scanner class object sc.close(); use for loop to copy elements from originalarray clonearray (int i="0;" < originalarray.length; clonearray[i]="originalArray[i];" display of the original array system.out.println('elements array:'); system.out.print(originalarray[i] + ' '); cloned system.out.println('
