The java.util.ArrayDeque.removeFirstOccurrence(Object) method in Java is used to remove the first occurrence of a specific element from this deque. If the element is present only once, then that element is removed and true is returned. If no such element is removed then false is returned.
Parameters: The method takes one parameter O of ArrayDeque type and refers to the element whose first occurrence is to be removed.
Return Value: This method returns true if the element is present in the map else it returns false.
Below programs illustrate the Java.util.ArrayDeque.removeFirstOccurrence() method:
Initial ArrayDeque: [Welcome, To, Geeks, For, Geeks] ArrayDeque after removing elements: [Welcome, To, Geeks]
Initial ArrayDeque: [10, 10, 30, 10, 30] ArrayDeque after removing elements: [10, 10, 10, 30]
