基本上我必须在我的程序中添加一个文本文件，并能够从文本文件中随机获取字符串，以便执行其他功能。能够玩刽子手游戏。任何人的帮助都会非常受欢迎。找到我的代码如何添加到它..
public class Main extends javax.swing.JFrame {
public ImageIcon imgs[];
public JButton btns[];

public int ran;

这是一个简单的程序，用于从文本文件中的随机位置获取单词：
public static void main(String[] args) {
String fileName = "/Users/[YOUR_NAME]/Desktop/words.txt"; //change to location of file
File wordList = new File(fileName);
List<String> words = new ArrayList<>();
Scanner reader = null;
try {
reader = new Scanner(wordList);
} catch (FileNotFoundException e) {
System.out.println("file \"" + fileName + "\" not found");
System.exit(0);
}
while(reader.hasNextLine()) {
String word = reader.nextLine();
words.add(word);
}
int place = rand.nextInt(words.size());
String s = words.get(place);
System.out.println("Random word from file: " + s);
}
只需将其合并到您的代码中即可。您可能需要进行一些小的更改，但这会给您答案。
