在Java中读取文本文件和将文本复制到数组中

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

public class FileUtil {
    public static void main(String[] args) {
        String filePath = "path/to/textfile.txt";
        List<String> lines = readFile(filePath);
        String[] array = copyToArray(lines);
        
        // 打印文本内容
        for (String line : array) {
            System.out.println(line);
        }
    }
    
    // 读取文本文件，返回每行内容的列表
    public static List<String> readFile(String filePath) {
        List<String> lines = new ArrayList<>();
        try (BufferedReader reader = new BufferedReader(new FileReader(filePath))) {
            String line;
            while ((line = reader.readLine()) != null) {
                lines.add(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return lines;
    }
    
    // 将文本内容复制到数组中
    public static String[] copyToArray(List<String> lines) {
        String[] array = new String[lines.size()];
        for (int i = 0; i < lines.size(); i++) {
            array[i] = lines.get(i);
        }
        return array;
    }
}
