Show me the code

// Create configuration
Configuration configuration = new ConfigBuilder("bash", "./script.sh")
    .setMasterLogFile(new File("~/masterlog.json"), Boolean.TRUE, Charset.defaultCharset())
    .enableLogStreaming(Boolean.TRUE).setParam("param1")
    .setParamList(Arrays.asList("param2", "param3"))
    .build();
{
  // Method 1 - start the runner at later point of time in sync and async manner.
  Runner runner = RunnerFactory.getRunner(configuration);
  Output output = runner.run();
  output = runner.runAsync().get();
}
{
  // Method 2 - Start instantly synchronously and async only.
  Output output = RunnerFactory.startProcess(configuration);
  output = RunnerFactory.startAsyncProcess(configuration).get();
}
