As we know there is an implementation of NavigableMap interface, known as TreeMap which also holds a key value pair but maintains the key sorted (natural order) in ascending order by default.Hence, to sort a HashMap by it's key it is only required to convert existing HashMap into a TreeMap.Apart from this, we can also define our custom sort order by implementing … In this quick tutorial, we'll learn how to sort a HashMap in Java.
