How do you bring information from 1 frame to another?

Question

I am doing a program that deals with customers going in the restaurant and ordering food using said program. On the first frame, it asks the customer what is his/her name and on the second frame, it will ask what are the orders. I've already built 5 frames and the final frame should display a summary of his orders and that includes the total amount the customer needs to pay and his/her name. How can I achieve that?

I'm only a beginner when it comes to coding and I might not know some of the terms that you will use so please be gentle. ^_^

Here are frames 1 and 2 and 5. I think this should be enough because frames 2, 3, and 4 are very similar. Frame2 is for the food, Frame3 is for the drinks, and Frame4 is for desserts. Take note that Frame5 is still not finished and might change depending on your answers. Please help me.

    Icon ic1=new ImageIcon("logo.jpg");
    JTextField tf1=new JTextField(10);
    JLabel lb2=new JLabel(ic1);
    JLabel lb3=new JLabel("Please press next to start ordering. ");



    public Frame1() {
        super("CHIONG'S 2 GO ORDERING SYSTEM");
