如何在Java中从consol应用程序中获取实时输出

Scanner scanner = new Scanner(System.in);
String input = scanner.nextLine();

PrintStream console = System.out;
console.println("Hello, World!");

ProcessBuilder processBuilder = new ProcessBuilder("your_command");
Process process = processBuilder.start();

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

// 获取子进程的输出流
OutputStream outputStream = process.getOutputStream();
PrintWriter writer = new PrintWriter(outputStream);

// 读取子进程的输出内容
String line;
while ((line = reader.readLine()) != null) {
    System.out.println(line);
}

// 向子进程发送输入内容
writer.println("input");
writer.flush();

// 等待子进程执行完毕
int exitCode = process.waitFor();
