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
