通過方法在不同類之間調用變量

Question

我正在為計算機科學課做作業。

我已經完成了很多分配工作，但是在從類中提取單個變量時遇到了一些麻煩。 我們只是進入類和對象，這是我們對它們的第一次分配，因此我並不完全理解所有這些。 到目前為止，我已經能夠打印出各個團隊，但是我還無法提取出個人的勝利，失敗，OTL和OTW，以便我可以計算出每個單獨的團隊是否都是獲勝的團隊。

到目前為止，我所做的是創建一個名為winningRecord和getPoints的類，該類返回一個布爾值，該布爾值決定是否是一支獲勝的團隊。 （一支獲勝球隊的公式是，如果得分是>玩過的游戲* 1.5（因為這是偶數記錄）。

我不知道如何獲取統計信息，因為它必須在HockeyTeam類中編寫。 我已經進行了設置，以便構造函數公開設置變量，以便可以訪問，但是就訪問它們而言，我感到很困惑。

至於一旦我能夠訪問它們就將它們存儲起來，我是否會制作一個並行方法來為每個團隊分配分數，而每個倉位僅分配一個數字？

這是所有代碼，感謝您的關注。

Answer 1

抱歉，但是從我的理解看來，您似乎無法理解您的部分問題，因為您似乎無法獲取個人的贏，輸，OTL和OTW。 我希望這能回答您的問題，如果不能，請澄清一下

1. 要訪問OTL，OTW，請執行以下循環：

    public class A1Q2fixed { public static void main(String[] parms) // main method { processHockeyTeams(); } /*****************************/ public static void processHockeyTeams() // processing method { boolean[] winningRecord; HockeyTeam[] hockeyTeams; hockeyTeams = createTeams(); printTeams(hockeyTeams); System.out.print("*********************\\n"); printWinningTeams(); winningRecord = HockeyTeam.winningRecord(hockeyTeams); for(HockeyTeam h:hockeyTeams) { System.out.println(h.losses);//To access and print losses System.out.println(h.otw);//To access and print otw System.out.println(h.otl);//To access and print otl } // printWinningTeams(hockeyTeams); } /*********************************/ public static void printTeams(HockeyTeam[] hockeyTeams) { for (int i = 0; i < hockeyTeams.length; i++) { System.out.println(hockeyTeams[i]); } } public static void printWinningTeams() { } public static HockeyTeam[] createTeams() { HockeyTeam[] teams; HockeyTeam team; int count; teams = new HockeyTeam[HockeyTeams.getNumberTeams()]; team = HockeyTeams.getTeam(); for (count=0; (count<teams.length) && (team!=null); count++) { teams[count] = team; team = HockeyTeams.getTeam(); } return teams; } } 

2. 同時在HockeyTeam中將名稱聲明為Static
