ArrayBlockingQueue clear() Method in Java

The clear() method of the ArrayBlockingQueue class in Java is used to remove all the elements from this queue.

The syntax is as follows

public void clear()

To work with ArrayBlockingQueue class, you need to import the following package

import java.util.concurrent.ArrayBlockingQueue;

The following is an example to implement clear() method of Java ArrayBlockingQueue class

Example

 Live Demo

import java.util.ArrayList;
import java.util.Iterator;
import java.util.concurrent.ArrayBlockingQueue;
public class Demo {
   public static void main(String[] args) throws InterruptedException {
      ArrayBlockingQueue<Integer> q = new ArrayBlockingQueue<Integer>(10);
      q.add(120);
      q.add(10);
      q.add(400);
      q.add(450);
      q.add(500);
      q.add(550);
      q.add(700);
      System.out.println("ArrayBlockingQueue = " + q);
      q.remove();
      System.out.println("Updated ArrayBlockingQueue = " + q);
      q.clear();
      System.out.println("Updated ArrayBlockingQueue = " + q);
   }
}

Output

ArrayBlockingQueue = [120, 10, 400, 450, 500, 550, 700]
Updated ArrayBlockingQueue = [10, 400, 450, 500, 550, 700]
Updated ArrayBlockingQueue = []
