13. Remove First and Last

Write a Java program to remove the first and last elements from a linked list.

Sample Solution:-

Java Code:

import java.util.*;

  public class Exercise13 {
  public static void main(String[] args) {
    // create an empty linked list
     LinkedList<String> l_list = new LinkedList<String>();
   // use add() method to add values in the linked list
          l_list.add("Red");
          l_list.add("Green");
          l_list.add("Black");
          l_list.add("Pink");
          l_list.add("orange");
      
     // print the list
   System.out.println("The Original linked list: " + l_list);

  // Remove the first element
    Object firstElement = l_list.removeFirst();
    System.out.println("Element removed: "+ firstElement);
 
  // Remove the last element
    Object lastElement = l_list.removeLast();
    System.out.println("Element removed: "+ lastElement);
    System.out.println("The New linked list: " + l_list);
  }
}

Sample Output:

The Original linked list: [Red, Green, Black, Pink, orange]            
Element removed: Red                                                   
Element removed: orange                                                
The New linked list: [Green, Black, Pink]
