Generic Linked List help. *Cannot convert from Object to type T

[MoozicFarm]

public class LinkedList<T> {
	
	
	public class Node<T>
	{
		T contents;
		Node next;
		
	}
	
	Node head, tail;
	
	public LinkedList()
	{
		head = new Node();
		tail = new Node();
		
		head.next =tail;
		tail.next = null;
	}
	
	public void addEnd(T element){
		
		Node newNode = new Node();
		newNode.contents = element;
		newNode.next = head.next;
		head.next = newNode;
	}
	
	public void addAt(int i, T element)
	{
		Node current = head;
		while(i>0){
			current = current.next;
			i--;
		}
		
		Node newNode = new Node();
		newNode.contents = element;
		newNode.next=current.next;
		current.next = newNode;
		
	}
	
	public T get(int i)
	{
		Node current = head;
		while(i>0)
		{
			current = current.next;
			i--;
		}
		
		return current.next.contents;
	}
	
	public T removeAndReturn(int i)
	{
		Node current = head;
		while(i>0){
			current = current.next;
			i--;
		}
		return current.next.contents;
		current.next = current.next.next;
	}
	
	public String toString()
	{
		StringBuilder S = new StringBuilder("");
		
		Node current = head;
		while(current != tail)
		{
			S.append(current.contents.toString() + " ");
			current = current.next;
		}
		return S.toString();
	}

}

So here is my linked list class. Not sure what the problem is but when i try and return the contents in getAt(int i) and removeAndReturn(int i) it is telling me that I cannot convert from an Object to type T. Not sure if i am just missing some syntax or what but any help would be appreciated. Any other errors you spot feel free to point out.

Thanks in advance,

Each element in a LikedList shoud have a reference to the next and to the previous element (except the first and the last element) of type Node. further you should have a other class that have the members first, last current of type Node and a member size of type int. This class shold have a method add(T), getSize() and so on to organize and administer your elements in the list.

You need to add lots of <T> to the required place in the code.

You need to add lots of <T> to the required place in the code.

Where do these <T>'s go? Can you show me with the removeAndReplace() method? I am having trouble figuring this out and I do not know why.

One spot would be Node definitions.

I'm still not following you!

You have define lots of Node variables without using generics. Change those definitions to use generics.
