In Java, we can use the TreeMap class to sort a map by its keys. This class is very handy to use. However, sometimes we need to sort a map by its values. How to sort a map by its values is a most frequently asked question by Java programmers.

a String). HashMap: this implementation uses a hash table as the underlying data structure. It implements all of the Map operations and allows null values and one null key. This class is roughly equivalent to Hashtable - a legacy data structure before Java Collections Framework, but it is not synchronized and permits nulls.

So as explanation-by-code, I'm looking for something that behaves like my fictitious OrderedMap: Java SortedMap can either be ordered according to the natural ordering of its keys or by providing a Comparator while creating map. If we don’t provide any Comparator (which should be able to accept key of the map) while creating SortedMap, all key elements of map must have implemented Comparable interface to ensure ordering.
