Java执行shell命令，如何实时读取输出？

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

public class ShellCommandExecutor {
    public static void main(String[] args) {
        try {
            // 执行shell命令
            ProcessBuilder processBuilder = new ProcessBuilder("your_shell_command");
            Process process = processBuilder.start();

            // 获取命令输出的输入流
            InputStream inputStream = process.getInputStream();
            BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));

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

            // 等待命令执行完成
            int exitCode = process.waitFor();
            System.out.println("命令执行完成，退出码：" + exitCode);

        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}
