Hash table and linked list implementation of the Map interface, with well-defined encounter order.C# 复制 [Android.Runtime.Register("java/util/LinkedHashMap", DoNotGenerateAcw=true)] [Java.Interop.JavaTypeParameters(new System.String[] { "K", "V" })] public class LinkedHashMap : Java....
Hash table and linked list implementation of theMapinterface, with predictable iteration order. This implementation differs fromHashMapin that it maintains a doubly-linked list running through all of its entries. This linked list defines the iteration ordering, which is normally the order in which ...
