LinkedList removeLast() Method in Java
The Java.util.LinkedList.removeLast() method is used to remove the last element from the LinkedList. This method also returns the element after removing it.
Syntax:
LinkedList.removeLast()
Parameters: This function does not take any parameters.
Return Value: The method returns the last element or the element present at the tail of the list.
Below program illustrate the Java.util.LinkedList.removeLast() method:
Java
// Java code to illustrate removeLast() import java.io.*; import java.util.LinkedList; public class LinkedListDemo { public static void main(String args[]) { // Creating an empty LinkedList LinkedList<String> list = new LinkedList<String>(); // Use add() method to add elements in the list list.add( "Geeks" ); list.add( "for" ); list.add( "Geeks" ); list.add( "10" ); list.add( "20" ); // Displaying the list System.out.println( "LinkedList:" + list); // Remove the tail using removeLast() System.out.println( "The last element is removed: " + list.removeLast()); // Displaying the final list System.out.println( "Final LinkedList:" + list); // Remove the tail using removeLast() System.out.println( "The last element is removed: " + list.removeLast()); // Displaying the final list System.out.println( "Final LinkedList:" + list); } } |
Output:
LinkedList:[Geeks, for, Geeks, 10, 20] The last element is removed: 20 Final LinkedList:[Geeks, for, Geeks, 10] The last element is removed: 10 Final LinkedList:[Geeks, for, Geeks]
Time complexity of removeLast() : O(1)
