Java: Retrieve but does not remove, the last element of a linked list

Java Collection, LinkedList Exercises: Exercise-21 with Solution

Write a Java program to retrieve, but not remove, the last element of a linked list.

Sample Solution:-

Java Code:

import java.util.*;

public class Exercise21 {
 public static void main(String[] args) {
  // create an empty linked list
  LinkedList <String> c1 = new LinkedList <String> ();
            c1.add("Red");
          c1.add("Green");
          c1.add("Black");
          c1.add("White");
          c1.add("Pink");
          System.out.println("Original linked list: " + c1);    
     // Retrieve but does not remove, the last element of a linked list
        String x = c1.peekLast();
    System.out.println("Last element in the list: " + x);
    System.out.println("Original linked list: " + c1);
    
 }
}

Sample Output:

Original linked list: [Red, Green, Black, White, Pink]                 
Last element in the list: Pink                                         
Original linked list: [Red, Green, Black, White, Pink]
