1- You have not overridden equals() and hashCode() methods of the
Obejct class in your class named MyClass. It is recommended that
when you are using your own class as a key,
you should give
definition to both the methods to compare when two objects should
be treated equals. What default implementation of the equals() says,
two objects are equal if their reference variable are referring to
the same object on the heap.
So far as your confusion of ordering is concerned: there is no
magic with get() method:
get method takes the object reference(key) and returns the value,
you confusion is running around the same;
you may be thinking that get is returning the objects in the same way
you have stored. But it is nothing like that,
you can try by changing the order:
There is nothing like order in the HashMap. And no order means no sorting
of course.
