Please help me understand this code

public class LinkedList {
    private class Node {
        private int value;
        private Node next;// what does this line do in this code
        public Node(int value){
            this.value = value;

That line is declaring a variable named next with the type of Node.

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).
