Program/Source Code:

The source code to get the last item from the LinkedList using the peekLast() method is given below. The given program is compiled and executed successfully.

// Java program to get the last item from the 
// LinkedList without removing it

import java.util.LinkedList;

public class Main {
  public static void main(String[] args) {
    LinkedList list = new LinkedList();

    list.add(1);
    list.add("TWO");
    list.add(3);
    list.add("FOUR");
    list.add(true);

    System.out.println("List Items: \n" + list);
    System.out.println("Last Item: " + list.peekLast());
  }
}

Output:

List Items: 
[1, TWO, 3, FOUR, true]
Last Item: true

Explanation:

In the above program, we imported the "java.util.LinkedList" package to use the LinkedList collection class. Here, we created a class Main. The Main class contains a main() method. The main() method is the entry point for the program.

In the main() method, we created an object of the LinkedList collection class to store different types of elements. Then we got the last element from the linked list using the peekLast() method of LinkedList and printed the result.
