Syntax:
Java
Java
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);
}
}
// Java code to illustrate clone() methodimport 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:
Example 2:
First ArrayList: [Geeks, for, Geeks, 10, 20] Second ArrayList is: [Geeks, for, Geeks, 10, 20]
// 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]
