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
