运行ProcessBuilder时的java问题-如何从外部文件获取要执行的命令？

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

public class ProcessBuilderExample {
    public static void main(String[] args) {
        List<String> commands = readCommandsFromFile("commands.txt");
        executeCommands(commands);
    }

    private static List<String> readCommandsFromFile(String filePath) {
        List<String> commands = new ArrayList<>();
        try (BufferedReader reader = new BufferedReader(new FileReader(new File(filePath)))) {
            String line;
            while ((line = reader.readLine()) != null) {
                commands.add(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return commands;
    }

    private static void executeCommands(List<String> commands) {
        for (String command : commands) {
            try {
                ProcessBuilder processBuilder = new ProcessBuilder(command);
                Process process = processBuilder.start();
                // 处理进程的输出结果等
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}
