Los siguientes programas ilustran el método ConcurrentSkipListSet.clear():
Programa 1:
/* Java Program Demonstrate clear()
method of ConcurrentSkipListSet() */
import java.util.concurrent.*;
class ConcurrentSkipListSetClearExample1 {
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: " + Lset);
// Clear the set
Lset.clear();
// Printing elements of the set after clear operation
System.out.println("After clear operation the set contains: "
+ Lset);
}
}
Producción:
The set contains: [10, 20, 30, 40, 50] After clear operation the set contains: []
Programa 2:
/* Java Program Demonstrate clear()
method of ConcurrentSkipListSet() */
import java.util.concurrent.*;
class ConcurrentSkipListSetClearExample2 {
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: " + Lset);
// Clear the set
Lset.clear();
// Printing elements of the set after clear operation
System.out.println("After clear operation the set contains: "
+ Lset);
}
}
Producción:
The set contains: [alex, bob, chuck, drake, eric] After clear operation the set contains: []
