    how to create/connect to a new windows/frame after pressing button next
    Do you want to create an instance of a new class in the button's listener method? Use the new statement with a constructor for the class to be created.

    Are you asking how to use the new statement to create an instance of a class?
    The posted code is full of usages of the new statement. For example:
     lblName = new JLabel ("Name: ");  //  create instance of JLabel class

    Could you explain what your problem is?

    Please post all code that is part of the problem on the forum. No links.

    Create an instance of the frame and use the reference to that instance to call its methods.

    Can you post the contents of the .rar because many people (myself included) will not open a .rar for security reasons. You can use only the 1 JFrame you have and place the contents of the other window in a JOptionPane or a JDialog. I tend to prefer this design because it's simpler, don't need to juggle JFrames and JOptionPane forces the user to interact in it (i.e. they cannot get focus by trying to click outside of it). The JFrame would initially have its contents set to invisible and once the user enters something correct or does something in the JOptionPane or JDialog, verify it and make the JFrame contents visible. You can make them visible using the method .setVisible(Boolean : boolean), where true makes it visible, false makes it invisible.

    Alternatively, you can have multiple JFrames by creating instances of each and calling upon their references to get the methods as Norm mentioned.

    if(e.getSource() == btnNxt). Use "==" here instead of "=" otherwise it won't work.

    it should be if(e.getSource() == btnNxt)
    {
    Car mycar = new Car() //This is the new window that you want to open. it may be anyclass.
    }
