運動員類

運動場地類 /** 比賽場地* */ public class PlayingField {/*** 開始比賽* * @param sportsman* @param sportsman2* @param ID*/public void start(Sportsman sportsman, Sportsman sportsman2, int ID) {// 0<=Math.random()<1// 隨機抽取一個數0 1 2// 0:sportsman 獲勝 1:sportsman2獲勝 2：平局int random = (int) (Math.random() * 3);switch (random) {case 0: {SportsEvents sportsEvents = sportsman.map.get(ID);ScoreRule scoreRule = sportsEvents.new ScoreRule();scoreRule.flag = "勝利";sportsEvents.setFlag(scoreRule);sportsman.setScore(sportsEvents);SportsEvents sportsEvents2 = sportsman2.map.get(ID);ScoreRule scoreRule2 = sportsEvents2.new ScoreRule();scoreRule2.flag = "失敗";sportsEvents2.setFlag(scoreRule2);sportsman2.setScore(sportsEvents2);}break;case 1: {SportsEvents sportsEvents = sportsman.map.get(ID);ScoreRule scoreRule = sportsEvents.new ScoreRule();scoreRule.flag = "失敗";sportsEvents.setFlag(scoreRule);sportsman.setScore(sportsEvents);SportsEvents sportsEvents2 = sportsman2.map.get(ID);ScoreRule scoreRule2 = sportsEvents2.new ScoreRule();scoreRule2.flag = "勝利";sportsEvents2.setFlag(scoreRule2);sportsman2.setScore(sportsEvents2);}break;case 2: {SportsEvents sportsEvents = sportsman.map.get(ID);ScoreRule scoreRule = sportsEvents.new ScoreRule();scoreRule.flag = "平局";sportsEvents.setFlag(scoreRule);sportsman.setScore(sportsEvents);SportsEvents sportsEvents2 = sportsman2.map.get(ID);ScoreRule scoreRule2 = sportsEvents2.new ScoreRule();scoreRule2.flag = "平局";sportsEvents2.setFlag(scoreRule2);sportsman2.setScore(sportsEvents2);}break;default:break;}} } 測試類：
