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
