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.LinkedList.clone() method:
// Java code to illustrate clone() method import java.io.*;
import java.util.LinkedList;
public class LinkedListDemo {
public static void main(String args[]) {
// Creating an empty LinkedList
LinkedList<String> list = new LinkedList<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 LinkedList:" + list);
// Creating another linked list and copying
LinkedList sec_list = new LinkedList();
sec_list = (LinkedList) list.clone();
// Displaying the other linked list
System.out.println( "Second LinkedList is:" + sec_list);
}
} |
Output:
First LinkedList:[Geeks, for, Geeks, 10, 20] Second LinkedList is:[Geeks, for, Geeks, 10, 20]
