This order is reflected when iterating over the sorted map's collection views (returned by the entrySet, keySet and values methods). Several additional In Java, Is there an object that acts like a Map for storing and accessing key/value pairs, but can return an ordered list of keys and an ordered list of values, such that the key and value lists a SortedMap is an interface in the collection framework. This interface extends the Map interface and provides a total ordering of its elements (elements can be traversed in sorted order of keys). The class that implements this interface is TreeMap. - Java Map with Insertion Order. In Java, we can use LinkedHashMap to keep the insertion order..
