### Creating a Linked List in Java

In this exercise, we will guide you through building a simple linked list by using a `Node` class in Java. The process involves allowing users to enter multiple names and organizing these names in a linked list based on the order of entry. The following steps explain how the program works:

1. **User Input for Names:**
   - Prompt the user to enter as many names as they wish.

2. **Building the Linked List:**
   - Utilize the `Node` class provided below to construct the linked list.

3. **Displaying the List:**
   - Print the entire list of names entered by the user.

4. **Removing an Item:**
   - Inquire which name the user wishes to remove from the list.
   - Remove the specified node from the list.

5. **Final Output:**
   - Print the updated list after the specified name has been removed.

```java
public class Node {
    public String data;
    public Node next = null;

    public Node(String data, Node next) {
        this.data = data;
        this.next = next;
    }

    public Node(String data) {
        this(data, null);
    }

    public String toString() {
        return data;
    }
}
```

By following the steps and utilizing the provided `Node` class, you will successfully manage a basic linked list, enabling modifications such as node removal. This exercise serves as a foundational introduction to data structures in Java programming.
