El método clear() de PriorityBlockingQueue elimina todos los elementos de esta cola. Por lo tanto, este método se puede aplicar cuando se requiere para borrar PriorityBlockingQueue.
Sintaxis:
public void clear()
Parámetro:
Este método no toma parámetros.
Devoluciones:
este método no devuelve nada.
Excepción:
este método no arroja ninguna excepción.
El programa a continuación ilustra la eliminación de todos los elementos de PriorityBlockingQueue usando el método clear().
Ejemplo 1:
// Java Program to Demonstrate clear() method
// of PriorityBlockingQueue.
import java.util.concurrent.PriorityBlockingQueue;
public class GFG {
public static void main(String[] args)
{
// define capacity of PriorityBlockingQueue
int capacity = 15;
// create object of PriorityBlockingQueue
PriorityBlockingQueue<Integer> PrioBlockingQueue
= new PriorityBlockingQueue<Integer>(capacity);
// add numbers
PrioBlockingQueue.add(78758575);
PrioBlockingQueue.add(63447688);
PrioBlockingQueue.add(56434788);
// print queue after add operation
System.out.println("After Adding Numbers:");
System.out.println("PriorityBlockingQueue:"
+ PrioBlockingQueue);
// remove all the elements using clear() method
PrioBlockingQueue.clear();
// print queue after clear operation
System.out.println("\nAfter clear operation:");
System.out.println("PriorityBlockingQueue:"
+ PrioBlockingQueue);
}
}
After Adding Numbers: PriorityBlockingQueue:[56434788, 78758575, 63447688] After clear operation: PriorityBlockingQueue:[]
Ejemplo 2: para ilustrar el método claro en PriorityBlockingQueue que contiene una lista de nombres.
// Java Program to Demonstrate clear() method
// of PriorityBlockingQueue.
import java.util.concurrent.PriorityBlockingQueue;
public class GFG {
public static void main(String[] args)
{
// define capacity of PriorityBlockingQueue
int capacity = 15;
// create object of PriorityBlockingQueue
PriorityBlockingQueue<String> PrioBlockingQueue
= new PriorityBlockingQueue<String>(capacity);
// add some names
PrioBlockingQueue.add("Tandrima");
PrioBlockingQueue.add("Argha");
PrioBlockingQueue.add("Arka");
// print queue after add operation
System.out.println("List of Names:");
System.out.println("PriorityBlockingQueue: "
+ PrioBlockingQueue);
// remove all the elements using clear() method
PrioBlockingQueue.clear();
// print queue after clear operation
System.out.println("\nAfter clearing List of names:");
System.out.println("PriorityBlockingQueue:"
+ PrioBlockingQueue);
}
}
List of Names: PriorityBlockingQueue: [Argha, Tandrima, Arka] After clearing List of names: PriorityBlockingQueue:[]
