BlockingDeque putLast() function in Java with Examples
The putLast(E e) method of BlockingDeque inserts the specified element into the queue represented by this deque (in other words, at the tail/end of this deque). If the Deque is capacity restricted, then it will wait for the space to become available.
public void putLast(E e)
Parameters: This method accepts a mandatory parameter e which is the element to be inserted at the end of the BlockingDeque.
Returns: This method does not return anything.
Exceptions: The program throws two exceptions as shown below:
- NullPointerException – if the specified element is null
- InterruptedException – if interrupted while waiting
Note: The putLast() method of BlockingDeque has been inherited from the LinkedBlockingDeque class in Java.
Below programs illustrate putLast() method of BlockingDeque:
