  +--Skater.Skater

public class Skater

extends java.lang.Object

Field Summary

static double	MAX_SCORE
static double	MIN_SCORE

Constructor Summary

Skater()
Creates a default new instance of Skater

Skater(java.lang.String nam, java.lang.String nation)
Creates a new instance of Skater with name and country known

Method Summary

boolean	equals(java.lang.Object obj) report whether two skaters are considered the same Need a policy decision here For now, consider them the same if they have the same name and country
double	getArtRating() Calculate and report the skater's total artistic rating This involves dropping high and low score and getting sum of rest Assumes that any Skater has array of Artistry Scores, even if the scores themselves havn't been altered from default 0
java.lang.String	getCountry() report skater's country
java.lang.String	getName() report skater's name
double	getNthArtScore(int n) report Nth judge's score for this skater on artistry if invalid N is passed, for now return -1 In future, once we cover exception handling, throw an exception
double	getNthTechScore(int n) report Nth judge's score for this skater on technical skill if invalid N is passed, for now return -1 In future, once we cover exception handling, throw an exception
static int	getNumJudges() static method to get how many judges there are
double	getTechRating() Calculate and report the skater's total technical rating This involves dropping high and low score and getting sum of rest Assumes that any Skater has array of Tech Scores, even if the scores themselves havn't been altered from default 0
double	getTotalRating() calculate and report skater's total score - artistic + technical
int	hashCode() Calculate a hash code for a Skater Object Overrides Object version From what I understand, in order to make some collections classes work, if you override toString / equals you should override hashCode (Unfortunately, my decisions on toString and equals are not consistent with each other :-) )
static void	main(java.lang.String[] args)
void	setCountry(java.lang.String nam) change skaters country Assumes country is ok, regardless Could use a lookup in fancier class
void	setName(java.lang.String nam) change skaters name Assumes name is ok, regardless
boolean	setNthArtScore(int n, double score) set a particular judge's score for the skater for artistry Reject change if invalid judge number or invalid score
boolean	setNthTechScore(int n, double score) set a particular judge's score for the skater for artistry Reject change if invalid judge number or invalid score
static boolean	setNumJudges(int num) Change the number of judges Policy Decision: Don't accept change if there have been skaters created Could be controversial - we might have different competitions with different numbers of judges but in that case, we should make numJudges non-static
java.lang.String	toString() give an output friendly representation of the skater Overrides Object version Policy decision: show name, country, artistic and technical ratings if available, and total if available
