Frage

I have a dynamic application that need to create a window interface with checkbox. The values of the checkboxes will control the next steps of the program.

So I have that interface with the button and I should select the buttons that I want then press a "RUN" button (in the moment of the choice the program must be waiting). How can I do that?

(I cannot use a server application with html tags. It would be too easy.)

This is my code. The problem is that the program controls the values of the checkboxes before I press the RUN button. So all the button states result in FALSE.

public class JRadiobuttonExample extends JFrame {
private JCheckBox radioButton1;
private JCheckBox radioButton2;
private JCheckBox radioButton3;
private JLabel label;
int i, state[] =  {0,0,0,0};
JCheckBox b[]; 
static ArrayList<Boolean> check=new ArrayList<Boolean>();
JButton altervista=new JButton("RUN");
static int num;


public JCheckBox[] getB() {
    return b;
}
public void setB(JCheckBox[] b) {
    this.b = b;
}
public ArrayList<Boolean> getCheck() {
    return check;
}
public void setCheck(ArrayList<Boolean> check2) {
    check = check2;
}
public JRadiobuttonExample(int num, ArrayList<String> lbl) {
    super("JRadiobuttonExample");
    getContentPane().setLayout(new FlowLayout(FlowLayout.CENTER));

    b= new JCheckBox[num];

    CheckBoxListener ckListener = new CheckBoxListener();

    for(i=0; i<num; i++) {
        b[i] = new JCheckBox(lbl.get(i));
        b[i].addItemListener(ckListener); 
        getContentPane().add(b[i]);
    }

    setVisible(true); 

    getContentPane().add(altervista);
    getContentPane().setVisible(true);
    Ascoltatore asc=new Ascoltatore();
    altervista.addActionListener(asc);
}

class Ascoltatore extends WindowAdapter implements ActionListener{
    public void windowClosing(WindowEvent e){

    }
    public void actionPerformed(ActionEvent e){
        if(e.getSource()==altervista){

        }
    }
}



public static void main(String argv[])
{
    ArrayList<String> col=new ArrayList<String>();

    col.add("hello");
    col.add("everyone");

    num=col.size();
    JRadiobuttonExample b = new JRadiobuttonExample(num,col);
    JCheckBox[] buttons=b.getB();

    for (JCheckBox c:buttons){
        check.add(c.isSelected());
    }

    System.out.println("checkbox values are:");
    for (boolean sel:check ){
        System.out.println(sel);
    }
}
}
