Write a Java Program to Check if a queue contains a specific element

The Java code demonstrates how to use the Queue interface with the LinkedList class to add elements to a queue and then check if the queue contains a specific element using the contains() method.

A Queue interface is implemented using the LinkedList class to create a queue to store integers.
Several integer elements (10, 23, 2, 18, 17) are added to the queue using the add() method.
The code defines a variable elecheck with the value 23. This is the element we want to check if it exists in the queue.
The contains() method is used to check if the specific element (elecheck) exists in the queue. It returns a boolean value (true or false) depending on whether the element is found or not.
The code then prints whether the queue contains the specified element or not, based on the boolean result from the contains() method.

Source Code

import java.util.LinkedList;
import java.util.Queue;
 
public class QueueContainsElement
{
	public static void main(String[] args)
	{
		Queue<Integer> queue = new LinkedList<>();
 
		// Adding elements to the queue
		queue.add(10);
		queue.add(23);
		queue.add(2);
		queue.add(18);
		queue.add(17);
 
		// Checking if the queue contains a specific element
		int elecheck = 23;
 
		boolean ele = queue.contains(elecheck);
 
		if(ele)
		{
			System.out.println("The Queue Contains " + elecheck);
		}
		else
		{
			System.out.println("The Queue Does Not Contain " + elecheck);
		}
    }
}

Output

The Queue Contains 23
