The java.util.concurrent.ConcurrentSkipListSet.spliterator() method is an in-built function in Java which returns a weakly uniform Spliterator across the elements of this set.
Syntax:
ConcurrentSkipListSet.spliterator()
Parameters: The function does not accept any parameter.
Return Value: The function returns a Spliterator across the elements of this set.
Below programs illustrate the ConcurrentSkipListSet.spliterator() method:
Program 1:
// Java Program Demonstrate Spliterator()// method of ConcurrentSkipListSet  import java.util.Spliterator;import java.util.concurrent.ConcurrentSkipListSet;  class ConcurrentSkipListSetSpliteratorExample1 {    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("best!!");          // spliterator split and iterate        // the split parts in parallel        Spliterator<String> str = set.spliterator();          // performs the action for each remaining element        str.forEachRemaining(            (n) -> {                String lc = n.toUpperCase();                System.out.println(" Lower case = " + n);                System.out.println(" Upper case = " + lc);                System.out.println();            });    }} |
Output:
Lower case = Gfg Upper case = GFG Lower case = best!! Upper case = BEST!! Lower case = is Upper case = IS
Program 2:
// Java Program Demonstrate Spliterator()// method of ConcurrentSkipListSet  import java.util.Spliterator;import java.util.concurrent.ConcurrentSkipListSet;  class ConcurrentSkipListSetSpliteratorExample2 {    public static void main(String[] args)    {        // Initializing the set        ConcurrentSkipListSet<Character> set =                          new ConcurrentSkipListSet<Character>();          // Adding elements to this set        for (char ch = 'A'; ch <= 'Z'; ch++) {            set.add(ch);        }          // Printing elements in the set        System.out.print("The elements in the set are : ");          // spliterator split and iterate        // the split parts in parallel        Spliterator<Character> str = set.spliterator();          // if element exists tryAdvance() will perform action        while (str.tryAdvance((n) -> System.out.print(n + " ")))            ;    }} |
Output:
The elements in the set are : A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
