如何在Jframe表单类中调用另一个类？

Question

I have a Jframe form class like this

  public class LoginForm extends javax.swing.JFrame 

In this,i get username & password from user and then send it to php server for validation and will get the response as OK or Invalid User. I have another class named ' public class LoginTimer implements Runnable' . In this class i have some code to execute. I want that in ' LoginForm ' when i got response as OK, the control will move to second class ' LoginTimer ' means second class will be
called. please tell me how to do it??
=====================================================================

 private void sendGet(String username,String pwd) throws Exception
{
      String url = "http://localhost/login.php?username="+username+ "&password="+pwd;
      final String USER_AGENT = "Mozilla/5.0";
      URL obj = new URL(url);
      HttpURLConnection con = (HttpURLConnection) obj.openConnection();
      con.setRequestMethod("GET");
      con.setRequestProperty("User-Agent", USER_AGENT);
      int responseCode = con.getResponseCode();
      System.out.println("\nSending 'GET' request to URL : " + url);
      System.out.println("Response Code : " + responseCode);
      BufferedReader in = new BufferedReader(
      new InputStreamReader(con.getInputStream()));
      String inputLine;
      StringBuffer response = new StringBuffer();
      while ((inputLine = in.readLine()) != null) 
      {
        response.append(inputLine);
      }
      in.close();
     //print result
       String r=response.toString();
      System.out.println("String "+r);
      if(r.equals("OK"))
      {
          System.out.println("you are a valid user");

      }
      else
      {
          System.out.println("You are an invalid user");
      }


 }

Below is my code for LoginTimer class. In this, I am getting names of visible windows and then thread starts and in run() method i call sendGet() method for sending window names to php server page. I want that when I got the OK response in LoginForm class,the LoginTimer class will be called and executed automatically.I mean, when user logged in & verified then sending of window names to php server will start automatically.

public class LoginTimer implements Runnable
{ 
 LoginTimer lk1;
 String s3;
 static int arraySize=10;
 static int arrayGrowth=2;
 static String[] m=new String[arraySize];
 static int count=0;

   @Override
   public void run()
   {
      for(int ck=0;ck<3;ck++)
      {File file=new File("G:\\check.txt");
      Scanner scanner = null;
      try
      {
         scanner = new Scanner(file);
      }
      catch (FileNotFoundException ex)
      {
         Logger.getLogger(LoginTimer.class.getName()).log(Level.SEVERE, null, ex);
      }

      while(scanner.hasNext())
      {
       String[] tokens = scanner.nextLine().split(":");
       String last = tokens[1];
      // System.out.println(last);
        if(last!=null)
        {
           try 
           {
              lk1.sendGet(last,m);

           }
           catch (Exception ex) 
           {
              Logger.getLogger(LoginTimer.class.getName()).log(Level.SEVERE, null, ex);
           }
        }
      } 
        try {
            Thread.sleep(5000);
        } catch (InterruptedException ex) {
            Logger.getLogger(LoginTimer.class.getName()).log(Level.SEVERE, null, ex);
        }
      }

   }

Answer 1

As u are implementing runnable class you are creating thread. So create an object of LoginTimer as LoginTimer lt = new LoginTimer(); in LoginForm class after you get result from php page.

Now call

   lt.start(); 

after ur creation of object ; which will call ur run method of thread.

Now in ur LoginTimer class override the run method like

   class LoginTimer implements Runnable
   {
   public void run()
   {
   //put your code which you want to execute now ... 
   }
   }

Answer 2

As your class implements java.lang.Runnable.

To have the run() method executed by a thread, pass an instance of your class_implementing_Runnable to a Thread in its constructor.Something like

Thread thread = new Thread(new LoginTimer());
   thread.start();
