java - 通过方法在不同类之间调用变量

Question

我正在为我的计算机科学课做作业。

我已经完成了相当多的作业，但是我在从类中提取单个变量时遇到了一些麻烦。我们刚刚进入类和对象，这是我们关于它们的第一个任务，所以我不完全理解它。到目前为止，我已经能够打印出球队，但我无法得出个人的胜负、OTL 和 OTW，以便我可以计算每个团队是否是获胜团队。

到目前为止我所做的是创建一个名为 winningRecord 和 getPoints 的类，它返回一个 boolean 值来决定它是否是获胜的团队。 (获胜球队的公式是积分 > 玩过的场数 * 1.5(因为这是一个偶数记录)。

我不知道如何提取统计数据，因为它必须写在 HockeyTeam 类中。我已经设置它以便构造函数公开设置变量以便可以访问，但就访问它们而言，我很困惑。

至于一旦我能够访问它们就将它们存储起来，我是否会制作一个并行方法，让每个团队都有积分，每个箱子只分配一个数字？

这里是所有的代码，感谢您的观看。

public class A1Q2fixed {
    public static void main(String[] parms) { // main method
        processHockeyTeams();
    }

    /*****************************/

        System.out.print("*********************\n");
        printWinningTeams();
        winningRecord = HockeyTeam.winningRecord(hockeyTeams);
        // printWinningTeams(hockeyTeams); 
    }

抱歉，我只能理解你问题的一部分，据我了解，你似乎无法访问个人赢、输、OTL 和 OTW。我希望这能回答你的问题，如果没有请澄清一下

1. 为了访问OTL，OTW有一个循环如下:

   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. 在 HockeyTeam 中也将名称声明为 Static
