了解互联网的人。我正在为第一年的编程课程完成一项任务，老实说，编程并不是我最好的技能。所以对这个小问题的任何帮助都会非常感激。
该程序本质上是一个数字猜谜游戏，它存储并将猜测分类到一个arraylist并显示，一旦你猜对了，平均，最低猜测，正确猜测的索引数组，平均值和转换华氏温度。它在9到40之间，因为作业指定了40，而且我的学生ID上的编号最高。当我可以简单地将它们放入一个类中时，不必要的类数量的原因也是赋值规范错误。
我遇到的麻烦是在arraylist中存储温度猜测，无论是正确的还是不正确的。我相信我已经在我的构造函数中正确初始化了arraylist但我不确定如何或从何处捕获jTextField的猜测。一旦我想到这一点，我就可以结合我为显示结果编写的其他方法，并完成这项任务。
再一次，我为我的一般新生事道歉，非常感谢任何帮助。

答案 0 :(得分：0)
1。首先创建一个Pojo来存储玩家的所有数据......
<强>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 ....
<强> //////////////////////////被修改///////////////// //////////////
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....
}
<强> ///////////////////////被修改//////////////////// ///////
好的......可以将int guessTemperature 添加到来自ArrayList 的JTextField而不使用POJO 就这样。
ArrayList<Integer> arList = new ArrayList<Integer>();
String str = jText.getText().toString();
int gTemp = Integer.parseInt(str);
arList.add(gTemp);
现在假设你有这个播放器有4个属性，比如TemperatureInput，Name，Age，Score ......等等...... N个玩家正在玩这个游戏......然后你应该使用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......来自另一个班级应该是这样......
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));
}
}
