Converting an Object list to a Queue

How do I convert a List of objects to a Queue and still be able to access their variables?

First I have a main class that creates instance classes of ClassTwo and gives them a unique ID (just hard coded it for the example)

public class ClassOne
{
	static List<ClassTwo> processList = new ArrayList<ClassTwo>();

	public static void main(String[] args)
	{
		processList.add(new Process(1));
		processList.add(new Process(2));
		processList.add(new Process(3));
	}
}

ClassTwo:

public class ClassTwo
{
	int id;

	public ClassTwo(int tempID)
	{
		id = tempID;
	}
}

How would I convert my List to a Queue so that I can still access each object's ID in class one?
I tried something like:

public class ClassOne
{
	static List<Process> processList = new ArrayList<Process>();
	public static Queue<Object> processQueue = new LinkedList<Object>();

	public static void main(String[] args)
	{
		processList.add(new Process(1));
		processList.add(new Process(2));
		processList.add(new Process(3));

		ConvertToQueue();
	}

	ConvertToQueue(List<Process> process)
	{
		//covert here..
	}
}

but I'm not sure exactly how to then convert it to a Queue, so i can still call variable 'id' from each ClassTwo object. Help would be appreciated!

You can use this :

Queue<Process> queue = new LinkedList<>(processList);

When you make this, you can still access to every element of the list, because they are all the same instances.
