我正在为学校做一个项目，我在这里遇到了一些麻烦。我要通过一个琐事游戏的文件。文件的格式如下：文件的第一行将是问题的类别，以下几行将是成对的问题和答案。直到它碰到一个空行，这表明空行之后的下一行开始一个新的类别并且它继续。我应该制作一个有 6 个索引的 ArrayList。每个类别一个，然后在每个索引中，我应该有一组问题和答案，我将能够利用这些问题和答案进行比较。我想本质上是一个数组列表中的一个数组。我希望我试图完成的事情是有意义的。这让我很困惑。但这里是我试图工作的代码，有这么多部分我变得非常混乱。
import java.util.ArrayList;
public class TriviaQuestion {
private String player;
private String category;
private String question;
private String answer;
private int score = 0;
/**
*
*/
public TriviaQuestion() {
player = "unknown";
category = "unknown";
question = "unknown";
answer = "unknown";
score = 0;
}
public TriviaQuestion(String category, String question, String answer){
}
public TriviaQuestion(String question, String answer){
}
public TriviaQuestion(String player, String category, String question,
String answer, int score) {
super();
this.player = player;
this.category = category;
this.question = question;
this.answer = answer;
this.score = score;
}
/**
* @return the player
*/
public String getPlayer() {
return player;
}
/**
* @param player the player to set
*/
public void setPlayer(String player) {
this.player = player;
}
/**
* @return the category
*/
public String getCategory() {
return category;
}
/**
* @param category the category to set
*/
public void setCategory(String category) {
this.category = category;
}
/**
* @return the question
*/
public String getQuestion() {
return question;
}
/**
* @param question the question to set
*/
public void setQuestion(String question) {
this.question = question;
}
/**
* @return the answer
*/
public String getAnswer() {
return answer;
}
/**
* @param answer the answer to set
*/
public void setAnswer(String answer) {
this.answer = answer;
}
/**
* @return the score
*/
public int getScore() {
return score;
}
/**
* @param score the score to set
*/
public void setScore(int score) {
this.score = score;
}
/* (non-Javadoc)
* @see java.lang.Object#toString()
*/
@Override
public String toString() {
return "TriviaQuestion [category=" + category + ", question="
+ question + ", answer=" + answer + "]";
}
}
然后是测试人员，我试图在课堂上记下一些关于它的笔记，但在这一点上它们对我来说没有多大意义。
