类名称：Deque
方法名：removeFirstOccurrence

Deque.removeFirstOccurrence介绍

[英]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 (o==null ? e==null : o.equals(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).
[中]从此数据集中删除指定元素的第一个匹配项。如果deque不包含该元素，则该元素将保持不变。更正式地说，删除第一个元素e，使得（o==null？e==null:o.equals（e））（如果存在这样的元素）。如果此deque包含指定的元素，则返回true（或者如果此deque因调用而更改，则返回等效值）。
