? ? 卡牌數(shù)據(jù)獲取（用了jxl）

public void setBlueCard() {//創(chuàng)建workbookWorkbook workbook= null;try {workbook = Workbook.getWorkbook(new File("G:/JavaStudy2/cardData/blueCard.xls"));} catch (IOException e) {e.printStackTrace();} catch (BiffException e) {e.printStackTrace();}//獲取第一個工作表sheetSheet sheet=workbook.getSheet(0);//獲取數(shù)據(jù)for (int i=0;i<sheet.getRows();i++){for (int j=0;j<sheet.getColumns();j++){Cell cell=sheet.getCell(j,i);blueCard.add(cell.getContents()+"");}}workbook.close();}public List<String> getBlueCard() {return blueCard;}

保底設置和抽卡結(jié)果判斷（太粗糙了

public class Raffle {private int count;private int countPurple;private int countGold;private double purplePercent;private double goldPercent;Raffle(){count = 1;countGold = 1;countPurple = 1;purplePercent = 0.1;goldPercent = 0.06;}private double getRandom(){return Math.random();}//抽卡結(jié)果判斷private String getAnswer(){double chance = getRandom();boolean isGold = getGold(chance);boolean isPurple = getPurple(chance);if(isGold){countGold = 1;goldPercent = 0.06;count++;countPurple = countPurple < 10?(countPurple+1):10;return "gold";}else if(isPurple){countGold++;count++;countPurple = 1;return "purple";}else{countPurple++;countGold++;count++;return "blue";}}private boolean getGold(double chance){//保底機制if(countGold >= 76) goldPercent += 0.08;return chance <= goldPercent;}private boolean getPurple(double chance){//保底機制if(countPurple == 10)return true;return chance <= purplePercent;}

抽卡流程

private List<String> blue;private List<String> purple;private List<String> gold;private int blueLength;private int purpleLength;private int goldLength;PickCard(){blue = new Card().getBlueCard();blueLength = blue.size();purple = new Card().getPurpleCard();purpleLength = purple.size();gold = new Card().getGoldCard();goldLength = gold.size();}private double getRandom(){return Math.random();}public String getCard(String ans){if(ans.equals("gold")){int a = (int)(getRandom()*goldLength);return gold.get(a);}else if(ans.equals("purple")){int a = (int)(getRandom()*purpleLength);return purple.get(a);}else{int a = (int)(getRandom()*blueLength);return blue.get(a);}}

最后調(diào)用

public class TEST {Raffle raffle = new Raffle();PickCard pick = new PickCard();private void tenTimesPick(){int count = 10;while (count-- > 0){String color = raffle.pickCard();System.out.println("[" + color + "]" + pick.getCard(color));}}private void singlePick(){String color = raffle.pickCard();System.out.println("[" + color + "]" + pick.getCard(color));}}

效果（咋還是非酋艸

加油優(yōu)化

總結(jié)
