List集合

这里用Java的List集合来实现这道题的答案存储与展示，提供两种常见实现方式：基于ArrayList的纯答案列表、以及存储自定义对象的嵌套信息列表，代码简洁且贴合题目场景。

方式1：纯答案列表（按题号顺序）

用ArrayList<String>存储答案，遍历输出题号与对应单词：

import java.util.ArrayList;

import java.util.List;

public class HomeworkAnswers {

public static void main(String[] args) {

// 创建List集合存储1-10空的答案

List<String> answers = new ArrayList<>();

answers.add("diverse");

answers.add("wide");

answers.add("especially");

answers.add("insulting");

answers.add("disposition");

answers.add("message");

answers.add("inadvertently");

answers.add("visitor");

answers.add("distressed");

answers.add("understood");

// 遍历输出每个题号的答案

for (int i = 0; i < answers.size(); i++) {

System.out.println("第" + (i + 1) + "空：" + answers.get(i));

}

}

}

方式2：存储单词信息的自定义对象列表

创建WordInfo类封装题号、单词、释义，用ArrayList<WordInfo>存储更完整的信息：

import java.util.ArrayList;

import java.util.List;

// 自定义类封装单词信息

class WordInfo {

private int num; // 题号

private String word; // 单词

private String meaning;// 释义

// 构造方法

public WordInfo(int num, String word, String meaning) {

this.num = num;

this.word = word;

this.meaning = meaning;

}

// 重写toString用于输出

@Override

public String toString() {

return "第" + num + "空：" + word + "（" + meaning + "）";

}

}

public class WordListDemo {

public static void main(String[] args) {

List<WordInfo> wordList = new ArrayList<>();

// 添加题目中的单词信息

wordList.add(new WordInfo(1, "diverse", "多样的；不同的"));

wordList.add(new WordInfo(2, "wide", "广泛的；宽阔的"));

wordList.add(new WordInfo(3, "especially", "尤其；特别"));

wordList.add(new WordInfo(4, "insulting", "侮辱的；无礼的"));

wordList.add(new WordInfo(5, "disposition", "性情；性格"));

wordList.add(new WordInfo(6, "message", "信息；消息"));

wordList.add(new WordInfo(7, "inadvertently", "无意地；不经意地"));

wordList.add(new WordInfo(8, "visitor", "访客；游客"));

wordList.add(new WordInfo(9, "distressed", "苦恼的；心烦的"));

wordList.add(new WordInfo(10, "understood", "理解；明白（过去分词）"));

// 遍历输出所有信息

for (WordInfo info : wordList) {

System.out.println(info);

}

}

}
