Constructor Detail

Machine

public Machine(java.lang.String name,
       Food food,
       int capacity)

The constructor takes at least the name of the machine, the Food item it makes, and its capacity. You may extend it with other arguments, if you wish. Notice that the constructor currently does nothing with the capacity; you must add code to make use of this field (and do whatever initialization etc. you need).

Method Detail

makeFood

public void makeFood()
              throws java.lang.InterruptedException

This method is called by a Cook in order to make the Machine's food item. You can extend this method however you like, e.g., you can have it take extra parameters or return something other than void. It should block if the machine is currently at full capacity. If not, the method should return, so the Cook making the call can proceed. You will need to implement some means to notify the calling Cook when the food item is finished.

Throws:

java.lang.InterruptedException
