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]
