how to set timer before doing a action?

 private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {      
     char[] pass = pass1.getPassword();  
     String passString = new String(pass);
     String l = "1;"+jTextField1.getText()+"/"+passString+"/"; 

     try{
         a.connection_send(l); 
         \\HEREEE :  I want to wait here 2 secondes before continue and doing a.connection_get() 
         loginInfo = a.connection_get();


         if(Integer.parseInt(loginInfo) == 1) {
            home_page a = new home_page();
            a.setBounds(500, 200, 470, 330); 
         } else { 
            JOptionPane.showMessageDialog(null, "Wrong UserName or Password", "Alert !", JOptionPane.WARNING_MESSAGE);
            jTextField1.setText("");
            pass1.setText("");
         }
     } catch(Exception e) { 
         JOptionPane.showMessageDialog(null, "You Are not connected to Server !\nPlease check Your netowrk ", "Alert !", JOptionPane.WARNING_MESSAGE);
     }
 }

How can i set a timer in the below code .. i marked where i want to place a little timer .. any idea to do that ? My objective is to wait a little bit until server is ready to send me the data .. so i can receive the proper data !

The most simple solution is to use the Thread.sleep(long milliseconds) method. It throws an InterruptedException if the current thread is interrupted for some reason. Sample usage is as follows:

try {
  Thread.sleep(2000); //2000 milliseconds = 2 seconds
} catch (InterruptedException e) {
  e.printStackTrace();
}

IMPORTANT: Note that Thread.sleep(int milliseconds) in Swing thread will make the GUI freeze! You should move all code in the jButton1ActionPerformed() method ActionPerformed to another thread to run.

You can use insert Thread.sleep(2000), which causes your application to pause for 2,000 milliseconds (i.e. 2 seconds). Note that this will have to appear in a try block that caches an InterruptedException, which gets thrown if another thread interrupts this one while it is sleeping.
