ArrayList clone() method in Java with Examples
The Java.util.ArrayList.clone() method is used to create a shallow copy of the mentioned array list. It just creates a copy of the list.
Syntax:
ArrayList.clone()
Parameters: This method does not take any parameters.
Return Value: This function returns a copy of the instance of Linked list.
Below program illustrate the Java.util.ArrayList.clone() method:
Example 1:
// Java code to illustrate clone() method  import java.io.*;import java.util.ArrayList;  public class ArrayListDemo {      public static void main(String args[])    {          // Creating an empty ArrayList        ArrayList<String> list            = new ArrayList<String>();          // Use add() method        // to add elements in the list        list.add("Geeks");        list.add("for");        list.add("Geeks");        list.add("10");        list.add("20");          // Displaying the list        System.out.println("First ArrayList: "                           + list);          // Creating another linked list and copying        ArrayList sec_list = new ArrayList();        sec_list = (ArrayList)list.clone();          // Displaying the other linked list        System.out.println("Second ArrayList is: "                           + sec_list);    }} |
Output:
First ArrayList: [Geeks, for, Geeks, 10, 20] Second ArrayList is: [Geeks, for, Geeks, 10, 20]
Example 2:
// Java code to illustrate clone() method  import java.io.*;import java.util.ArrayList;  public class ArrayListDemo {      public static void main(String args[])    {          // Creating an empty ArrayList        ArrayList<Integer> list            = new ArrayList<Integer>();          // Use add() method        // to add elements in the list        list.add(10);        list.add(20);        list.add(30);        list.add(40);        list.add(50);          // Displaying the list        System.out.println("First ArrayList: "                           + list);          // Creating another linked list and copying        ArrayList sec_list = new ArrayList();        sec_list = (ArrayList)list.clone();          // Displaying the other linked list        System.out.println("Second ArrayList is: "                           + sec_list);    }} |
Output:
First ArrayList: [10, 20, 30, 40, 50] Second ArrayList is: [10, 20, 30, 40, 50]
