The removeLastOccurrence() method of BlockingDeque removes the last occurrence of the specified element from this deque. If the deque does not contain the element, it remains unchanged. It returns true if this deque contained the specified element, else it returns false.
public boolean removeLastOccurrence(Object o)
Parameters: This method accepts a mandatory parameter o which specifies the element whose last occurrence is to be removed from the Dequeue container.
Returns: This method returns true if the element is present and removed from the Deque container, else it returns false.
Note: The removeLastOccurrence() method of BlockingDeque has been inherited from the LinkedBlockingDeque class in Java.
Below programs illustrate removeLastOccurrence() method of BlockingDeque:
Program 1: When element is present.
Blocking Deque: [15, 20, 20, 15] Last occurrence of 15 removed Blocking Deque: [15, 20, 20]
Program 2: When element is not present.
Blocking Deque: [15, 20, 20, 15] 10 not present and not removed Blocking Deque: [15, 20, 20, 15]
