The
clone()method of
java.util.concurrent.ConcurrentSkipListSetis 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
// Java Program Demonstrate clone()
// method of ConcurrentSkipListSet
import 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
// 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]Reference
