Examples of java.util.LinkedHashMap$LinkedHashMapEntrySet

java.util.LinkedHashMap
LinkedHashMap is a variant on HashMap. Its entries are kept in a doubly-linked list. The iteration order is, by default, the order in which keys were inserted.
If the three argument constructor is used, and order is specified as true, the iteration would be in the order that entries were accessed. The access order gets affected by put(), get(), putAll() operations, but not by operations on the collection views.
Null elements are allowed, and all the optional Map operations are supported.
