Write a Java program to remove an item from the Queue

The Java code represents a program that uses a Queue to store a list of colors and then removes an item from the queue. The Queue is implemented using a LinkedList. Let's go through the code step-by-step:

First, a Queue of strings called queue_list is created, and a LinkedList is used as its underlying implementation.
Several colors are added to the queue using the add() method.
The current state of the queue is printed using System.out.println().
The remove() method is called on the queue to remove the first item from the queue. The removed item is then printed using System.out.println().
Finally, the updated state of the queue (after removal) is printed again using System.out.println().

Source Code

import java.util.LinkedList;
import java.util.Queue;
public class RemoveItem
{
	public static void main(String[] args)
	{
		Queue < String > queue_list = new LinkedList < > ();
		queue_list.add("Yellow");
		queue_list.add("Green");
		queue_list.add("Pink");
		queue_list.add("Black");
		queue_list.add("Blue");
		queue_list.add("White");
		queue_list.add("Red");
 
		System.out.println("Queue before Removal : " + queue_list);
 
		System.out.println("Removed Item is : " + queue_list.remove());
 
		System.out.println("Queue after Removal : " + queue_list);
	}
}

Output

Queue before Removal : [Yellow, Green, Pink, Black, Blue, White, Red]
Removed Item is : Yellow
Queue after Removal : [Green, Pink, Black, Blue, White, Red]
