El método clear() de LinkedBlockingQueue elimina todos los elementos de esta cola. Después de aplicar este método, la cola quedará vacía.
Sintaxis:
public void clear()
Los siguientes programas ilustran el método clear() de la clase LinkedBlockingQueue:
Programa 1:
// Java Program Demonstrate clear()
// method of LinkedBlockingQueue
import java.util.concurrent.LinkedBlockingQueue;
public class GFG {
public static void main(String[] args)
{
// define capacity of LinkedBlockingQueue
int capacityOfQueue = 50;
// create object of LinkedBlockingQueue
LinkedBlockingQueue<Integer> linkedQueue
= new LinkedBlockingQueue<Integer>(capacityOfQueue);
// Add element to LinkedBlockingQueue
linkedQueue.add(2300);
linkedQueue.add(1322);
linkedQueue.add(8945);
linkedQueue.add(6512);
// print queue
System.out.println("LinkedBlockingQueue before using"
+ " clear() : " + linkedQueue);
// Apply clear() method
linkedQueue.clear();
// print queue
System.out.println();
System.out.println("LinkedBlockingQueue after using"
+ " clear() method : " + linkedQueue);
}
}
Producción:
LinkedBlockingQueue before using clear() : [2300, 1322, 8945, 6512] LinkedBlockingQueue after using clear() method : []
Programa 2:
// Java Program Demonstrate clear()
// method of LinkedBlockingQueue
import java.util.concurrent.LinkedBlockingQueue;
public class GFG {
public static void main(String[] args)
{
// define capacity of LinkedBlockingQueue
int capacityOfQueue = 50;
// create object of LinkedBlockingQueue
LinkedBlockingQueue<String> names
= new LinkedBlockingQueue<String>(capacityOfQueue);
// Add element to ArrayBlockingQueue
names.add("Shubham");
names.add("Siddhant");
names.add("Mahafuj");
names.add("Arka");
names.add("Raunak");
// print queue
System.out.println("LinkedBlockingQueue before using"
+ " clear() : " + names);
// Apply clear() method
names.clear();
// print queue
System.out.println();
System.out.println("LinkedBlockingQueue after using"
+ " clear() method : " + names);
}
}
Producción:
LinkedBlockingQueue before using clear() : [Shubham, Siddhant, Mahafuj, Arka, Raunak] LinkedBlockingQueue after using clear() method : []
