A question about JOptionPane.showOptionDialog()?

Question

one problem confused me.
import javax.swing.*;
class Test
public Test()
     int n;
     String title;
     Object[] message = new Object[3];
     Object[] obj = new Object[2];
     message[0] = "Name ";
     message[1] = "Age";
     title = "Information";
     obj[0] = "OK";
     obj[1] = "Cancel";
     n = JOptionPane.showOptionDialog(null,
     message,
     title,
JOptionPane.OK_CANCEL_OPTION,
          JOptionPane.INFORMATION_MESSAGE,
                    null,
                    obj,
                    obj[0]);               
     public static void main(String[] args)
          new Test();
i run the java compiler in command line.
c:\proj1>javac Test.java
c:\proj1>java Test
Having done the program, i found that command line didnot return to "c:\proj1>"
only after "Ctrl-c" can that return back to the "c:\proj1". i didnot meet this problem when i run other java projects.
what's the problem?
thanks!

Implement a call to System.exit(0) at the point you want the programm to close.
(Depending on the return code of your option dialog)
