在 Java 集合中，哪个集合不允许重复，哪个还保留数据的插入顺序？
最佳答案
LinkedHashSet
This implementation differs from HashSet in that it maintains a doubly-linked list running through all of its entries. This linked list defines the iteration ordering, which is the order in which elements were inserted into the set (insertion-order)
