如何使用ProcessBuilder让BufferedReader显示正在运行的python脚本的实时输出？

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

public class PythonProcess {
    public static void main(String[] args) {
        try {
            // 创建ProcessBuilder对象，并指定要执行的命令
            ProcessBuilder pb = new ProcessBuilder("python", "your_script.py");
            // 启动进程
            Process process = pb.start();

            // 获取进程的输入流
            InputStream inputStream = process.getInputStream();
            BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));

            // 实时读取输出并显示
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }

            // 等待进程执行结束
            int exitCode = process.waitFor();
            System.out.println("Process exited with code " + exitCode);
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}
