We've seen how to remove an item from a specific index from LinkedList.  In this tutorial, we'll see how to delete the first and last item in a LinkedList.

The LinkedList class has two methods:

1) public Object removeFirst(): Deletes and returns the first item in the list.
2) public Object removeLast(): deletes and returns the last item in the list.

Example:

import java.util.LinkedList; 

public class RemoveFirstLast {

 public static void main(String[] args) {
 
 LinkedList llist = new LinkedList(); 

 llist.add("First"); 
 llist.add("e2"); 
 llist.add("e3"); 
 llist.add("e4"); 
 llist.add("Last"); 

 System.out.println("Before deletion: "+llist); 
 
 String first = llist.removeFirst(); 
 //first deleted item
 System.out.println("deleted item: "+first); 

 System.out.println("After deletion(first): "+llist); 
 
 String last = llist.removeLast(); 
 //last deleted item
 System.out.println("deleted item: "+last); 

 System.out.println("After deletion(last): "+llist); 
 }
}

Output:

Before deletion: [First, e2, e3, e4, Last]
item removed: First
After deletion(first): [e2, e3, e4, Last]
item removed:  Last
After deletion(last): [e2, e3, e4]
