public boolean removeFirstOccurrence(Object o) Implements java.util.Deque.removeFirstOccurrence. Doc from java.util.Deque.removeFirstOccurrence. Removes the first occurrence of the specified element from this deque. If the deque does not contain the element, it is unchanged. More formally, removes the first element `e` such that `Objects.equals(o, e)` (if such an element exists). Returns `true` if this deque contained the specified element (or equivalently, if this deque changed as a result of the call). Parameters o:Object element to be removed from this deque, if present Returns:boolean `true` if an element was removed as a result of this call Annotations @Override

public boolean removeFirstOccurrence(Object o)

Implements java.util.Deque.removeFirstOccurrence.

Doc from java.util.Deque.removeFirstOccurrence.

Parameters

o:Object: element to be removed from this deque, if present

Returns:boolean

true if an element was removed as a result of this call

removeLast	back to summary
public E removeLast() Implements java.util.Deque.removeLast. Doc from java.util.Deque.removeLast. Retrieves and removes the last element of this deque. This method differs from `pollLast` only in that it throws an exception if this deque is empty. Returns:E the tail of this deque Annotations @Override

public E removeLast()

Implements java.util.Deque.removeLast.

Doc from java.util.Deque.removeLast.

Retrieves and removes the last element of this deque. This method differs from pollLast only in that it throws an exception if this deque is empty.
