HashMap to Call a Method

Hi Guys, I'm new to this forum , and Really need some help

I'm working under BlueJ as this is how the university is teaching us

I have a program that when you type "Circle" to the Console , the Circle will appear (See Below)
Attachment 1611

This is done because I have a method that makes the circle visible and a execute to call it

Attachment 1612

Now I want to be able to use a HashMap (as required for the task) and be able to add more Options such as "move.Left" or "move.Right" when I type Circle move left or Circle move right into the console
I tried so many things!
Really need advice.

Thanks

What code do you have now and what questions do you have about how to change the code to do what you want it to do?
Be sure to wrap posted code with code tags:

what questions do you have about how to change the code to do what you want it to do?

Well, The question says, Improve the program so You have more option such as move the circle left or right, when typing into the terminal window.
at the moment I can just make the circle appear when typing the word "circle"

--- Update ---

They Also advice you to use a HashMap

Describe the steps the changed program needs to take to solve the problem.
What problems are you having coding those steps?

What does the program do with what the user types in? What more does it need to do?
