Not able to run same test case on multiple device

Issues/Bugs
1

I am trying to run same test case on multiple emulators. I am passing two ports and UDID to create sessions for each devices.Also creating two threads for each device.

Here is my code :

public class StartingSteps implements Runnable{
private AppiumDriverLocalService appiumService;
int port;
String udid;

public StartingSteps(int portNumber, String udid) {
this.port = portNumber;
this.udid = udid;
}
Runnable r1 = new StartingSteps(4700,“udid_of_firstdevice”); //device id of first mobile device
Runnable r2 = new StartingSteps(5000,“udid_of_seconddevice”); //device id of second mobile device
new Thread(r1).start();
new Thread(r2).start();
@Override
public void run() {
}

public void initialize(String udid)
{
    String osName = System.getProperty("os.name");
    System.out.println("started");
   if (osName.contains("Mac")) {
        appiumService = AppiumDriverLocalService.buildService(new AppiumServiceBuilder()
                .usingDriverExecutable(new File(“node_path”))
               // .withAppiumJS(new File(“appium_path”))
                .withIPAddress("127.0.0.1")
                .usingPort(port)
                .withArgument(GeneralServerFlag.ROBOT_ADDRESS,udid)
                .withArgument(AndroidServerFlag.BOOTSTRAP_PORT_NUMBER, String.valueOf(port+2))
                .withArgument(GeneralServerFlag.SESSION_OVERRIDE)
                 .withLogFile(new File("target/{"+udid+"}.log")));
    }
    appiumService.start();
    DesiredCapabilities cap = new DesiredCapabilities();
    cap.setCapability(MobileCapabilityType.PLATFORM_NAME, MobilePlatform.ANDROID);
    cap.setCapability(MobileCapabilityType.PLATFORM_VERSION, "5.1");
    cap.setCapability(MobileCapabilityType.DEVICE_NAME, "Android Device");
    cap.setCapability("app", “app_path/Goibibo.apk");
    cap.setCapability("appPackage", “package_name”);
    cap.setCapability("appActivity", “activity_name”);
    cap.setCapability("autoAcceptAlerts", true);
    cap.setCapability("newCommandTimeout", 30);

    try {
        driver = new AndroidDriver(new URL("http://127.0.0.1:"+port+"/wd/hub"), cap);
    } catch (MalformedURLException e) {
        e.printStackTrace();
    }
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
  
}   @After
public void tearDown(Scenario scenario) {
        driver.quit();
        appiumService.stop();
}
}

But code is not getting compiled.It is giving exception
