Methods

Constructor

The constructor accepts parameters for 'xCoord', 'yCoord', and 'maxCapacityBase'.

It uses 'this' to access the values for 'xCoord' and 'yCoord' of the object and sets the values to those passed. In this case 'this' is used to determine if we mean the parameter called 'xCoord' or the variable called 'xCoord'.

'capacity' is set by multipling 'maxCapacityBase' by '0.6', is 60% of 'maxCapacityBase'.

'maxCapacity' takes the 'maxCapacityBase' and is set by adding a random number between 0 and 50, and then subtracting a random number between 0 and 50.

'dailyCosts' are set using the following calculation:

dailyCosts = maxCapacityBase * 0.2 + capacity * 0.5 + 100

Finally the 'NewDay' method is run.

GetCapacity

This will just return the capacity stored in 'capacity'.

GetX

This will just return the value of 'xCoord'.

GetY

This will just return the value of 'yCoord'.

AlterDailyCost

This accepts a parameter called 'amount' (a double), this method will just add the value of 'amount' to the 'dailyCosts' variable.

AlterCapacity

This method accepts a parameter for the 'change' required.

The 'oldCapacity' is stored, and then the capacity is updated by adding the 'change'.

If this causes 'capacity' to be high than 'maxCapacity', then 'capacity' is reset to the 'maxCapacity'. and the actual amount of change is returned.

The 'else if' then checks to make sure capacity is not below 0. If so 'capacity' is set to zero.

The daily costs are recalculated using the formula:

maxCapacity * 0.2 + capacity * 0.5 + 100

Finally the value for 'change' is returned.

IncrementVisits

This method will just increment the 'visitsToday' variable using 'visitsToday++'.

NewDay

This will just reset the 'visitsToday' back to 0.

CalculateDailyProfitLoss

This method will accept parameters for 'avgPricePerMeal' and 'avgCostPerMeal'. It will then return the result of this calcualtion:

(avgPricePerMeal - avgCostPerMeal) * visitsToday - dailyCosts

GetDetails

This declares a new string called 'details' which is then used to concatenate several bit of information together.

This string is then returned.
