The removeFirstOccurrence() method of LinkedBlockingDeque removes the first 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 removeFirstOccurrence(Object o)
Parameters: This method accepts a mandatory parameter o which specifies the element to be removed from the Deque container.
Returns: This method returns true if the element is present and removed from the Deque container, else it returns false.
Below programs illustrate removeFirstOccurrence() method of LinkedBlockingDeque:
Program 1: When element is present
Linked Blocking Deque: [15, 20, 20, 15] Fist occurrence of 15 removed Linked Blocking Deque: [20, 20, 15]
Program 2: When element is not present
Linked Blocking Deque: [15, 20, 20, 15] 10 not present and not removed Linked Blocking Deque: [15, 20, 20, 15]
