How To Avoid Flickering When Calling Another Swing Frame

I am trying to call another swing frame from my current frame. And after calling second frame i dispose the current frame.

But while second frame coming on the screen, current frame gets dispose and second frame takes some seconds to appear on screen.

So its creating a bad flickering effect on screen and its not suitable for my application.

I want that first frame will call sencond frame and it will not look like second frame is called. I just want to cancel flickering effect.

Here is my source code.

1st Frame:

public class Welcome extends JFrame {
JFrame f;
JTextArea nameField,nameField1;
JLabel lable;

[Code] .....
