Food Order Scheduler

Objective:

During a busy lunch, a chef must cook orders while minimizing the average waiting time per customer. Unfortunately the chef only can cook the orders one at a time. Using a min-heap, schedule food orders based on their shortest cooking times in order to get the best average waiting times.

Lab Solution

• Functionality. (80pts)
• No Syntax Errors. (80pts*)
• *Code that cannot be compiled due to syntax errors is nonfunctional code and will receive no points for this entire section.
• Set up the Project. (10pts)
• First download the driver file and include it in your project.
• Do not modify the driver.
• Create a class Order (10pts)
• Implements Type Comparable
• Instance Variables
• Customer: A non-null String representing the name of the customer. Default value is “none”.
• Food Order: A non-null String representing the name of the food the customer has ordered. Default value is “none”.
• Cooking Time: A positive whole number which represents the number of minutes it takes to cook the order. Default value is 1.
• Arrival Time: A positive whole number which represents when (in minutes) the order was placed. Default value is 0.
• Cooking Time Left: A positive whole number which represents the amount of time left to cook the food in minutes. This value is always initially set to be the same as Cooking Time.
• Constructors
• Default: Must set all properties to their default values mentioned in the “Instance Variables” section.
• Parameterized: Must take in a parameter for each instance variable in the order named above. This means the first instance variable is the first parameter, the second instance variable is the second parameter, and so on; EXCEPT for Cooking Time Left. This must set the instance variable values only if the given values are valid, but otherwise it must set the instance variables to their default values.
• Methods
• Accessors for the instance variables.
• All must be written for full credit.
• Mutators for the instance variables.
• Make sure in the mutators check for valid values named in the “Instance Variables” Section.
• toString: This method returns a String with some of the instance variable values concatenated together with the format:

Customer: <<customer’s name>>, Order: <<order’s name>>, Cooking Time Left: <<cooking time left>>

Where values in “<<>>” correspond to variable values.

• compareTo: returns an integer value based on the Cooking Time. Shorter times have a higher priority than longer times.
• cookForOneMinute: This method subtracts one from the Cooking Time Left. Also it takes in no values and returns no values.
• isDone: This method returns true or false based on if the Cooking Time Left is equal to 0.
• toString: This method returns a string value containing the Customer’s name, their order, and the cooking time left.
• All the above must apply for full credit.
• Create a class MinHeap (30pts)
• A generic implementation of an Array-Based, Minimum Heap
• Methods
• add: Takes in a new element via a parameter and adds it to the heap
• remove: Removes and returns the first element in the heap.
• All above must apply for full credit.
• Create a class OrderScheduler (30pts)
• Instance Variables:
• Orders: a MinHeap of type Order representing the orders waiting to be cooked.
• Current Order: The current order that is being cooked. This value is separate from the heap.
• Current Minute: The current simulated minute, which by default is 0.
• Total Orders: A running total of the number of orders that has been added. Default value is 0.
• Summed Waiting Times: The total summed waiting times for each order. Default value is 0.
• Methods
• addOrder: This method takes in an instance of an order, and if the current order is null then the newly added order is assigned to it. Otherwise, it adds the new order to the heap of orders. In either case the total orders is increased by one.
• advanceOneMinute: This method adds one to the current minute counter, and then cooks the current order for one minute. If the order is now done, then calculate its waiting time by taking the difference from the current minute and the current order’s arrival time. This value should be added to the summed waiting times. Next replace the current order with the order on top of the heap.
• isDone: This method returns true or false based on if the current order is null
• getAverageWaitingTime: This returns a decimal value corresponding to the division of the summed waiting times by the total orders.
• All the above must apply for full credit.
• Coding Style. (10pts)
• Code functionality organized within multiple methods other than the main method, and methods organized within multiple classes where appropriate. (5pts)
• Readable Code (5pts)
• Meaningful identifiers for data and methods.
• Proper indentation that clearly identifies statements within the body of a class, a method, a branching statement, a loop statement, etc.
• All the above must apply for full credit.
• Comments. (10pts)
• Your name in the file. (5pts)
• At least 5 meaningful comments in addition to your name. These must describe the function of the code it is near. (5pts)
