学习互联网的人。我目前正在为一年级的编程课做作业，老实说，编程并不是我最大的技能。因此，对于这个小问题的任何帮助将不胜感激。

该程序本质上是一个数字猜谜游戏，它将猜测存储和排序到一个数组列表中，一旦你猜对了，就会显示平均值、最低猜测、正确猜测的索引数组、平均值和转换后的华氏温度. 它在 9 到 40 之间，因为作业指定了 40 和我学生证上的最高数字。当我可以简单地将它们归为一个时，不必要的类数量的原因也是分配规范错误。

我遇到的麻烦是将温度猜测（无论正确与否）存储在数组列表中。我相信我已经在我的构造函数中正确初始化了数组列表，但我不确定如何或在哪里捕获来自 jTextField 的猜测。一旦我弄清楚这一点，我就可以合并我为显示结果编写的其他方法并完成这项任务。

再次，我为我的一般新手道歉，任何帮助将不胜感激。

1.首先创建一个Pojo来存储玩家的所有数据...

例如

public class Player{

    int prompt1;
    int prompt2;
    int userInput;
    String comment;
    int restart;

  }

2.然后将它们存储在ArrayList......

//////////////////////已编辑//////////////////// ////////

public class Player{

        int prompt1;
        int prompt2;
        int userInput;
        String comment;
        int restart;

    public Player(int p1, int p2, int usInput, String c, int res){

       this.prompt1 = p1;
       this.prompt2 = p2;
       this.userInput = usInput;
       this.comment = c;
       this.restart = res ;


    }

}

 public class Test{

   ArrayList<Player> arList = new ArrayList<Player>();

   arList(new Player(p1, p2, usInput, c,  res));  // These Arguments u must declare and initialize....


  }

///////////////////已编辑////////////////////// /

好的，可以在不使用 POJO的情况下将int guessTemperature添加到ArrayListfrom中，可以通过这种方式完成。JTextField 

ArrayList<Integer> arList = new ArrayList<Integer>();

String str = jText.getText().toString();

int gTemp = Integer.parseInt(str);

arList.add(gTemp);

现在假设你有这个 Player 有 4 个属性，比如 TemperatureInput、Name、Age、Score 等等......并且有 N 个玩家正在玩这个游戏......那么你应该使用 Pojo 和 Collection（即......列表，设置，地图）

public class Player{

    int guessTemp;
    String name;
    int age;
    long score;


    public Player(int gTemp, int name, int age, int score){

      this.guessTemp = gTemp;
      this.name = name;
      this.age = age;
      this.score = score;
    }

   public int getGuessTemp() {
        return guessTemp;
    }
    public void setGuessTemp(int guessTemp) {
        this.guessTemp = guessTemp;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public long getScore() {
        return score;
    }
    public void setScore(long score) {
        this.score = score;
    }


}

现在......从另一个班级应该是这样的......

public class Test{


public static void main(String[] args){

        ArrayList<Player> pList = new ArrayList<Player>();

       String name = jName.getText().toString();
       long score = Long.parseLong(jScore.getText().toString());
       int age =  Integer.parseInt(jAge.getText().toString());
       int gTemp = Integer.parseInt(jTemp.getText().toString());


       pList.add(new Player(gTemp, name, age, score));


   }


}
