I am trying to sort in alphabetical order a Linked List in java but my method only works with integers.

What I have tried:

public Node sort()

Node current;
Node sortedList = null;
int count;

if(first == null)
throw new IllegalArgumentException("List is empty");

// Creating a loop that will go through the whole list.
for (int index = 1; index < size(); index++)
// Redirects the unsorteNode variable to the second element in the list.
current =;

// Redriects the scan variable to index.
count = index;

// Creating a loop that will go thorught the list and swap values.
while (count > 0 && current.value.compareTo(first.value) > 0)
sortedList = new Node(current.value, first);
first =;
current =;

// Switches the values in its correct position. = current;

// Returns the sorted list.
return sortedList;

What is the definition of your node class, and how does the compareTo method operate?
