Return Value: The function returns a True boolean value.
Below programs illustrate the ConcurrentSkipListSet.add() method:
Program 1: Adding Integer in the set.
import java.util.concurrent.*;
class ConcurrentSkipListSetAddExample1 {
public static void main(String[] args)
{
ConcurrentSkipListSet<Integer> Lset =
new ConcurrentSkipListSet<Integer>();
for ( int i = 10 ; i <= 50 ; i += 10 )
Lset.add(i);
System.out.println( "The set contains: " );
for (Integer i : Lset)
System.out.print(i + " " );
}
}

ConcurrentSkipListSet<String> Lset =
new ConcurrentSkipListSet<String>();
Lset.add( "alex" );
Lset.add( "bob" );
Lset.add( "chuck" );
Lset.add( "drake" );
Lset.add( "eric" );
