The default behaviour of aTreeMapis to sort its elements in ascending order based on the keys. However, by using theCollections.reverseOrder()method in Java, we can create a TreeMap that maintains the elements inreverse order, allowing us to display them in descending order based on the key...
For up to Java Version 8: No, you will have to add all the elements manually. You can use an initializer in an anonymous subclass to make the syntax a little bit shorter: Map<String, String> myMap = new HashMap<String, String>() {{ put("a", "b"); put("c", "d"); }...

The order of a map is defined as the order in which the iterators on the map’s collection views return their elements.Some map implementations, like theTreeMapclass, make specific guarantees as to their order; others, like theHashMapclass, do not. ...
