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任务，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，所以我并不完全理解它们。到目前为止，我已经打印出了这些球队，但是我无法完成个人的胜利，失利，OTL和OTW，因此我可以计算每支球队是否都是一支成功的球队。

到目前为止，我所做的是创建一个名为winningRecord和getPoints的类，它返回一个布尔值，决定它是否是一个胜利的团队。（获胜团队的公式是，如果积分是＆gt;游戏播放* 1.5（因为这是一个偶数记录）。

我不知道如何提取统计数据，因为必须在HockeyTeam课程中编写。我已经设置了它，以便构造函数公开设置变量以便可以访问它，但是只要访问它们，我就难过了。

一旦我能够访问它们，只要存储它们，我是否只需要为每个团队创建一个具有分数的并行方法，每个分区只分配一个数字？

以下是所有代码，谢谢你们。

Answer 1

很抱歉，但我只能理解你问题的一部分，从我的理解，你似乎无法获得个人的胜利，损失，OTL和OTW。我希望这可以回答你的问题，如果没有请澄清一点

要访问OTL，OTW的循环如下：

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; 

 } 

}

在HockeyTeam中也将名称声明为静态

通过方法在不同类之间调用变量
