Write a Java program to Clear all elements from a queue

The Java code defines a class ClearQueue with a method clearQueue that clears all elements from a given Queue of integers.

The clearQueue method takes a Queue named queue as input and calls the clear() method on the queue. This method clears all elements from the queue, making it empty.
In the main method, a Queue named queue is created using the LinkedList implementation of the Queue interface. Integers are added to the queue using the offer() method.
The original queue is printed using System.out.println().
The clearQueue method is then called with the queue as an argument, which clears all elements from the queue.
Finally, the cleared queue is printed using System.out.println().

Source Code

import java.util.*;
 
public class ClearQueue
{
	public static void clearQueue(Queue<Integer> queue)
	{
		queue.clear();
	}
 
	public static void main(String[] args)
	{
		Queue<Integer> queue = new LinkedList<>();
		queue.offer(1);
		queue.offer(2);
		queue.offer(3);
		queue.offer(4);
		queue.offer(5);
 
		System.out.println("Original Queue : " + queue);
		clearQueue(queue);
		System.out.println("Cleared Queue : " + queue);
	}
}

Output

Original Queue : [1, 2, 3, 4, 5]
Cleared Queue : []
