ConcurrentSkipListSet size() method in Java
The java.util.concurrent.ConcurrentSkipListSet.size() method is an in-built function in Java which gives the total count of the elements present in the set.
Syntax:
ConcurrentSkipListSet.size()
Parameters: The function does not accept any parameter.
Return Value: The function returns the number of elements in the queue.
Below programs illustrate the ConcurrentSkipListSet.size() method:
Program 1:
import java.util.concurrent.ConcurrentSkipListSet;
class ConcurrentSkipListSetSizeExample1 {
public static void main(String[] args)
{
ConcurrentSkipListSet<Integer> set =
new ConcurrentSkipListSet<Integer>();
for ( int i = 1 ; i <= 10 ; i++)
set.add(i);
System.out.println( "Number of elements in the set = "
+ set.size());
System.out.println( "set : " + set);
}
}
|
Output:
Number of elements in the set = 10
set : [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
Program 2:
import java.util.concurrent.ConcurrentSkipListSet;
class ConcurrentSkipListSetSizeExample2 {
public static void main(String[] args)
{
ConcurrentSkipListSet<String> set =
new ConcurrentSkipListSet<String>();
set.add( "A" );
set.add( "B" );
set.add( "C" );
set.add( "D" );
set.add( "E" );
System.out.println( "Number of elements in the set = "
+ set.size());
System.out.println( "set : " + set);
}
}
|
Output:
Number of elements in the set = 5
set : [A, B, C, D, E]
