Task: (5 marks) Last year, the Chinese people were crazy of Tokyo Olympic diving competition because of a 14-year-old young girl who scored a few fantastic perfect 10's diving. A lot of us may wonder how they come up with the scores for the diving competition. It takes several steps to get from the judge ratings to the final scores, and the announcers are rarely eager to explain it. 1 Each judge rates the dive from 0 ("completely failed") to 10 ("excellent"). This is based on how well the diver performs, from his starting position to entry into the water. The judges do not take difficulty into account for this score. • Example: a diver receives execution scores of 6.5, 7.0, 7.0, 7.5, 7.5, 8.0, and 8.0. Note that the score is either *.0 or *.5 (* is from 0 to 10) Cross out the outliers: So cross out two scores on each end: 6.5, 7.0, 7.0, 7.5, 7.5, 8.0, and 8.0, i.e., remove the two top and two bottom scores Add the rest together. Find the sum of the remaining scores. •Example: 7.0 +7.5 +7.5 = 22.0 Multiply by the degree of difficulty (DD). Each attempted dive has a degree of difficulty calculated in advance. This is based on many factors, such as the number of twists and somersaults and the take-off and entry positions. Multiply your last sum by the degree of difficulty to get the final score for this dive. • Example: Let's say the diver attempted an inward 2½ somersault dive in the 10 meters competition, in the pike position. This has a difficulty score of 2.8. Multiply this by the execution score to get the final score: 22.0 x 2.8 = 61.6. In the competition, divers need to dive a few rounds, normally 5 rounds in final. Let us look at the UML diagram for this assignment: -String name -String player -int age Country +Country(String name, String player, int age) +String getName( +String getPlayer( +int getAge( +void setinfo(String name, String player, int age) Q-final String Countries Three classes: MainA3 -static void getScore(double score) -static String getCountry(ArrayList<Diving> alist, double result) -static void displaySorted List(ArrayList<Diving alist) -static double getDifficulty -static int getAge( -static void displayGameInfo(ArrayList<Diving > alist) -static void displayResultInfo(ArrayList<Diving > alist) -static void updateCFArray(ArrayList Diving> alist, double cfArray) + static void main(String args) static int SIZE -Country name -double score -double difficulty -double cf 4-double fs Diving +Diving (Country name, double score, double difficulty, double cf) +Country getCountry +double getDifficulty +double getCarriedForward( +double getFinalScore( +void setDifficulty(double difficulty) -ArrayList Double>getSortedList() -double highest() -double secondHighest() -double lowest -double secondLowest) double finalScore( double getTotalScore( +void printinfo() A class to describe a Country: name of the country, name of the player and the player's age. A class to describe a Diving: A constant SIZE (no of judges), a Country object, the scores given by all judges, the degree of difficulty, the carried forward scores (cf) and the final scores (fs). Most of methods are obvious in definition. The getSortedList stores the stores the scores in a list (a dummy list) and sort it; you can use it to retrieve the highest, second highest etc. scores. This method is optional, you can find your own way to solve the problem In main class, you define an array of countries to be used in the design. The countries can be duplicated. Let us look at the runtime analysis: Round: 1 Starting position Country China 2 Thailand China 1 South South Korea Japan LISA USA Australia Malaysia Russia Brazil Countries China 2 Thailand China 1 South Korea Dapan USA Australia Malaysia Russia Brazil The result is 1 Australia 2 Thailand Diver 2 Name 1 Name 2 Name Name 3 Home Name 4 Nome Name 5 Name Name 6 A 6 Name 7 Malaysia 10 Russia Name 8 Name 9 Name 10 USA Janar Japan China 1 Brazil China 2 South Korea Age 79.20 72.00 62.10 61.20 57.20 56.40 39.00 35.70 27.60 27.50 ទី១៩ ៩ខ ១ ឆ ជ ដ ង ៦ន 22 22 20 16 16 17 17 21 21 24 15 17 17 Difficulty 8.0 8.0 2.6 4.0 4.4 2.1 24 3.4 31 32 J3 34 35 2.0 7.0 0.5 9.5 4.0 4.0 4.0 10.0 2.0 5.5 5.5 7.0 6.0 3.0 2.0 1.0 4.0 8.0 0.0 7.0 3.0 7.0 2.8 2.0 8.0 7.5 5.5 5.5 5.5 1.5 5.5 7.8 9.0 9.0 7.0 1.5 1.0 1.5 6.8 0.5 6.0 6.8 6.0 0.5 10.0 8.5 4.5 0.0 0.5 1.0 4.5 1.0 3.0 7.5 5.5 0.5 0.0 6.5 5.0 8.5 6.0 1.0 4.6 18 4.8 4.6 2.5 4.7 36 37 Difficulty 9.5 8.0 7.0 7.5 10.0 6.0 2.0 6.0 3.0 3.0 9.5 2.6 4.0 4.4 2.1 3.4 3.4 4.6 4.8 4.6 2.5 4.7 Let us now look at the information of Round 2: c/f Current 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 39.00 72.00 57.20 35.70 61.28 61.20 62.10 79.20 27.60 27.50 56.40 Total 39.00 72.00 57.20 35.70 61.28 61.20 62.18 62.10 79.20 27.60 27.50 56.40 In Round 1, the panel divers' information, the country, the name of the diver, his / her age, and the level of difficulty.
