ArrayBlockingQueue toString() Method in Java

The toString() method in Java is used to return a string representation of the object. In the case of ArrayBlockingQueue, the toString() method returns a string representation of the elements in the queue.

Syntax:

public String toString()

Example:

import java.util.concurrent.ArrayBlockingQueue;

public class Main {
  public static void main(String[] args) {
    ArrayBlockingQueue<Integer> queue = new ArrayBlockingQueue<>(5);
    queue.add(1);
    queue.add(2);
    queue.add(3);
    queue.add(4);
    queue.add(5);
    System.out.println(queue.toString());
  }
}

Output:

[1, 2, 3, 4, 5]

In the above example, we have created an ArrayBlockingQueue of size 5 and added 5 elements to it. The toString() method is then called on the queue object, which returns a string representation of the elements in the queue. The output shows the elements in the queue enclosed in square brackets and separated by commas.
