要实现此目的，您可以使用ProcessBuilder类，如下所示：
File pathToExecutable = new File( "resources/external.exe" );ProcessBuilder builder = new ProcessBuilder( pathToExecutable.getAbsolutePath(), "-i", "input", "-o", "output");builder.directory( new File( "resources" ).getAbsoluteFile() ); // this is where you set the root folder for the executable to run withbuilder.redirectErrorStream(true);Process process = builder.start();Scanner s = new Scanner(process.getInputStream());StringBuilder text = new StringBuilder();while (s.hasNextLine()) { text.append(s.nextLine()); text.append("n");}s.close();int result = process.waitFor();System.out.printf( "Process exited with result %d and output %s%n", result, text );这是一堆代码，但是可以让您进一步控制流程的运行方式。
