Benefits:
• It supports variations in the traversal of a collection.
• It simplifies the interface to the collection.
Applicable Scenarios:
• Access to a collection object is required without having to expose its internal representation.
• Multiple traversals of objects need to be supported in the collection.
• A universal interface for traversing different structures needs to be provided in the collection.
博客介绍了迭代器遍历集合的好处,包括支持集合遍历的多样性、简化集合接口。还说明了其适用场景,如在不暴露集合内部表示的情况下访问对象、支持集合中对象的多次遍历,以及为集合中不同结构提供通用遍历接口。
