Method Detail

setupRace

public static void setupRace(double lapLength,
                             double miles)

This mutator method sets the track size and distance data for a race and must be called before calling updateRaceStats to add statistics for that race to any object. Lap length will give the length of a single lab in miles (track size); miles indicates the total length of the race. This method must be called exactly once for each race run and increases the count of the number of total races.

Parameters:

lapLength - Size of the track in miles

miles - Length of race in miles

updateRaceStats

public void updateRaceStats(int lapsLed,
                            int position)

This mutator method updates the individual driver statistics on laps led, average finish position.

Parameters:

lapsLed - Number of laps that this driver led the race

position - Position number at end of the race

avgFinish

public double avgFinish()

This accessor method calculates the average position of finish for this driver over the races in which the driver competed.

Returns:

average finish position of this driver

percentMilesLed

public double percentMilesLed()

This accessor method returns the percent of miles led by this driver as a percentage of the total miles of all races.

Returns:

The percent of this driver's led miles

getMilesLed

public double getMilesLed()

This accessor method returns the total miles led by this driver.

Returns:

The miles led by this driver.

getDriver

public java.lang.String getDriver()

This accessor method returns the name of this driver.

Returns:

This driver's name.

toString

public java.lang.String toString()

This method returns a string representation of this object. The format of the string is: "Driver:%s, Car:%d, Races:%d, AvgFin:%f, MilesLed:%f"

Overrides:

toString in class java.lang.Object

Returns:

A string representation of the object
