ConcurrentLinkedDeque getLast() Method in Java
The java.util.concurrent.ConcurrentLinkedDeque.getLast() method is an in-built method in Java which returns the last element of the deque container.
Syntax:
Conn_Linked_Deque.getLast()
Parameters: The method does not accept any parameter.
Return Value: The method returns the last element present in the Deque.
Exception: The function throws a NoSuchElementException when the deque is empty.
Below programs illustrate the ConcurrentLinkedDeque.getLast() method:
Program 1:
/* Java Program to Demonstrate getLast() method of ConcurrentLinkedDeque */ import java.util.concurrent.*;class GFG { public static void main(String[] args) { // Creating an empty Deque ConcurrentLinkedDeque<String> cld = new ConcurrentLinkedDeque<String>(); // Add elements into the Deque cld.add("Welcome"); cld.add("To"); cld.add("Geeks"); cld.add("4"); cld.add("Geeks"); // Displaying the Deque System.out.println("Elements in Deque: " + cld); // Displaying the Last element System.out.println("The Last element is: " + cld.getLast()); }} |
Output:
Elements in Deque: [Welcome, To, Geeks, 4, Geeks] The Last element is: Geeks
Program 2:
/* Java Program to Demonstrate getLast() method of ConcurrentLinkedDeque */ import java.util.concurrent.*;class GFG { public static void main(String[] args) { // Creating an empty Deque ConcurrentLinkedDeque<Integer> cld = new ConcurrentLinkedDeque<Integer>(); try { // Displaying the Last element System.out.println("The Last element " + "is: " + cld.getLast()); } catch (Exception e) { // Displaying the Exception System.out.println(e); } // Add elements into the Deque cld.add(12); cld.add(43); cld.add(29); cld.add(16); cld.add(70); // Displaying the Deque System.out.println("Elements in " + "Deque: " + cld); // Displaying the Last element System.out.println("The Last element is: " + cld.getLast()); }} |
Output:
java.util.NoSuchElementException Elements in Deque: [12, 43, 29, 16, 70] The Last element is: 70
