Answer 1

Here is a Java code snippet to insert an element at the beginning of a linked list and to remove the last element of the linked list:

```

import java.util.LinkedList;

public class LinkedListExample {

public static void main(String[] args) {

LinkedList<String> linkedList = new LinkedList<String>();

// Insert an element at the beginning of the linked list

linkedList.addFirst("First");

// Remove the last element of the linked list

linkedList.removeLast();

}

}

```

To insert an element at the beginning of a linked list, we can use the `addFirst()` method of the `LinkedList` class. This method adds the specified element at the beginning of the linked list. In the code above, we add the element "First" at the beginning of the linked list.

To remove the last element of a linked list, we can use the `removeLast()` method of the `LinkedList` class. This method removes and returns the last element of the linked list. In the code above, we remove the last element of the linked
