You need to post some code here, to show what efforts you have already made..
Whatever code you have implemented to get the outcome.. Or at least the idea you have.

You can get better inputs from other users.

By the way, I didn't post that example for a joke. It is indeed an immutable class, and it's the simplest possible example.

So now here's an exercise for you: Explain why it is immutable. (Hint: what does "immutable" mean? And does this class satisfy that definition?)
 
I will suppress my every urge. But not this shameless plug:
