    Default GUI Problem

    I'm making a GUI that has the user input a student's information into the GUI and then I write the information to a file.

    My problem is that the program doesn't seem to wait for the user to enter the information to continue the program....it just keeps executing the program, and then by the time the user enters the info the rest of the program has been executed.

    Here's my code:

    public static void main(String[] args)
            {
                    StudentData frame = new StudentData();
     
                    RandomAccessFile raf = null;
     
                    raf = frame.receiveFile();
     
                    frame.enterStudentData();
     
                    frame.setTitle("Student Data");
                    frame.setSize(1000,650);
                    frame.setLocationRelativeTo(null);
                    frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
     
                    frame.setVisible(true);
     
                    System.out.println("And the fname = " + frame.fname);
     
                    frame.outputStudentData(raf);
            }

    With GUI, you show a form with input fields and wait for the user to enter his input and tell the program that the input is ready to be retrieved from the form. A common way to do that is with a button the user can press.

    setVisible() doesn't wait. It displays the GUI and returns to the next statement.

    Thanks for the response!

    I understand what you're saying, but, unfortunately, I have no idea how to make the user click a button that signals the program to retrieve the information.

    I am totally new to GUI and I've been looking online but it seems like everything is really convoluted. Any advice?

    Take a look at the tutorial:
    Trail: Creating a GUI With JFC/Swing (The Java™ Tutorials)

    It's not something you can pickup in a few hours.
