属性值

实现
注解
具有固定大小的集合在创建之后不能再添加或移除元素,但是允许修改现有元素。A collection with a fixed size does not allow the addition or removal of elements after the collection is created, but it allows the modification of existing elements.
具有固定大小的集合就是一个集合,其中包含阻止添加和移除元素的包装;因此,如果对基础集合进行了更改,包括添加或删除元素,则固定大小的集合将反映这些更改。A collection with a fixed size is simply a collection with a wrapper that prevents adding and removing elements; therefore, if changes are made to the underlying collection, including the addition or removal of elements, the fixed-size collection reflects those changes.
