Removes the first occurrence of the specified element from this list, if it is present (optional operation). If this list does not contain the element, it is unchanged. More formally, removes the element with the lowest index i such that (o==null ? get(i)==null : o.equals(get(i))) (if such an element exists). Returns true if this list contained the specified element (or equivalently, if this list changed as a result of the call).
删除第一个出现的相同对象,判断时,需要使用equals方法,如果是自己创建的对象,需要重写类的hashCode和equals方法
本文深入解析了列表中删除指定元素的实现机制,重点讨论了如何使用equals方法进行对象比较,并强调了自定义类时重写hashCode和equals方法的重要性。
