The java.util.concurrent.ConcurrentSkipListSet.add() method is an in-built function in Java which is used to insert an element in this set.
Syntax:
ConcurrentSkipListSet.add(E e)
Parameters: The function accepts a single parameter e i.e. the element to be inserted.
Return Value: The function returns a True boolean value.
Below programs illustrate the ConcurrentSkipListSet.add() method:
Program 1: Adding Integer in the set.
// Java program to demonstrate add()// method of ConcurrentSkipListSet  import java.util.concurrent.*;  class ConcurrentSkipListSetAddExample1 {    public static void main(String[] args)    {        // Creating a set object        ConcurrentSkipListSet<Integer> Lset =                   new ConcurrentSkipListSet<Integer>();          // Adding elements to this set        for (int i = 10; i <= 50; i += 10)            Lset.add(i);          // Printing elements of the set        System.out.println("The set contains: ");        for (Integer i : Lset)            System.out.print(i + " ");    }} |
Output:
The set contains: 10 20 30 40 50
Program 2: Adding String in the set.
// Java program to demonstrate add()// method of ConcurrentSkipListSet  import java.util.concurrent.*;  class ConcurrentSkipListSetAddExample2 {    public static void main(String[] args)    {        // Creating a set object        ConcurrentSkipListSet<String> Lset =                      new ConcurrentSkipListSet<String>();          // Adding elements to this set        Lset.add("alex");        Lset.add("bob");        Lset.add("chuck");        Lset.add("drake");        Lset.add("eric");          // Printing elements of the set        System.out.println("The set contains: ");        for (String i : Lset)            System.out.print(i + " ");    }} |
Output:
The set contains: alex bob chuck drake eric
