Transfer of control from JFrame back to the calling class

I am making a project in which I have a class named runner_HMMPayl from the main of this class I am initiating a JFrame0 f instance. JFrame0 returns the values of text fields in JFrame0 that are then used in main.

I am facing a problem that when I instantiate the JFrame0, it keeps on running and control is not shifted back to main of runner_HMMPayl class. How can I do that?

These are the relevant code snippets.

First one is the main, making JFrame0 instance.

    public static void main(String[] args) throws IOException 
{
    JFrame0 f = new JFrame0();
    f.Start(f);
    System.out.println("f closed"); //not displayed in console----------
    System.out.println("First argument" + args[0]); //not displayed in console-
}

This is the code of the JFrame0 button, which upon pressing should return the arguments.

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
    argA[0]= "1";

    String s1 = jTextField1.getText();
    argA[1] = s1;
    String s2 = jTextField7.getText();
    argA[2] = s2;
    // ..
    String s7 = jTextField2.getText();
    argA[7] = s7;

    runner.configureHMMPayl(argA); //function in runner_HMMpayl class (instance:runner)
    runner.giveArgs(argA); //function in runner_HMMpayl class 
 }

I am not able to figure it out.

Use a modal JDialog to stop execution until the dialog is closed.

See How to make Dialogs for more details.
