The clone() method of java.util.concurrent.ConcurrentSkipListSet is an in-built function in Java which returns a shallow copy of this ConcurrentSkipListSet instance.
Syntax:
ConcurrentSkipListSet.clone()
Parameters: The function does not accept any parameter.
Return Value: The function returns a shallow copy of ConcurrentSkipListSet.
Below programs illustrate the ConcurrentSkipListSet.clone() method:
Program 1:
// Java Program Demonstrate clone()// method of ConcurrentSkipListSetimport java.util.concurrent.*; class ConcurrentSkipListSetCloneExample1 { public static void main(String[] args) { // Initializing the set ConcurrentSkipListSet<Integer> set = new ConcurrentSkipListSet<Integer>(); // Adding elements to this set for (int i = 10; i <= 15; i++) set.add(i); // Printing elements of the set System.out.println("The set contains: " + set); // Cloning the ConcurrentSkipListSet ConcurrentSkipListSet<Integer> clone_set = set.clone(); // Adding elements to the clone set clone_set.add(16); // Printing elements of the clone set System.out.println("The clone set contains: " + clone_set); }} |
Output:
The set contains: [10, 11, 12, 13, 14, 15] The clone set contains: [10, 11, 12, 13, 14, 15, 16]
Program 2:
// Java Program Demonstrate clone()// method of ConcurrentSkipListSet */import java.util.concurrent.*; class ConcurrentSkipListSetCloneExample2 { public static void main(String[] args) { // Initializing the set ConcurrentSkipListSet<String> set = new ConcurrentSkipListSet<String>(); // Adding elements to this set set.add("Gfg"); set.add("is"); set.add("fun"); // Printing elements of the set System.out.println("The set contains: " + set); // Cloning the ConcurrentSkipListSet ConcurrentSkipListSet<String> clone_set = set.clone(); // Adding elements to the clone set clone_set.add("site"); // Printing elements of the clone set System.out.println("The clone set contains: " + clone_set); }} |
Output:
The set contains: [Gfg, fun, is] The clone set contains: [Gfg, fun, is, site]
