如何更优雅地从Java文件中提取字符串？

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class StringExtractor {
    public static void main(String[] args) {
        String filePath = "path/to/your/java/file.java";
        List<String> extractedStrings = extractStringsFromFile(filePath);
        
        for (String str : extractedStrings) {
            System.out.println(str);
        }
    }
    
    public static List<String> extractStringsFromFile(String filePath) {
        List<String> extractedStrings = new ArrayList<>();
        
        try (BufferedReader reader = new BufferedReader(new FileReader(filePath))) {
            StringBuilder fileContent = new StringBuilder();
            String line;
            
            while ((line = reader.readLine()) != null) {
                fileContent.append(line).append("\n");
            }
            
            String regex = "\"([^\"]*)\"";
            Pattern pattern = Pattern.compile(regex);
            Matcher matcher = pattern.matcher(fileContent.toString());
            
            while (matcher.find()) {
                extractedStrings.add(matcher.group(1));
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        
        return extractedStrings;
    }
}
