How to increase any of the above variables by one? Hint: first, you can use the public getter to obtain the current value of the variable, and then increase this value by one, and then use the public setter to set this increased value back to the variable. And that is why we provide each variable with a public setter and getter in step 1 above. In order to call the public getter and setter, you need to first obtain an instance (handler) of the class Bloodstream.

I will presume that Bloodstream is your subclass of World. You can use the following line to access it:
?
1
Bloodstream bloodstream = (Bloodstream)getWorld();
The you can call the methods on 'bloodstream.
