java - Cancel selecting a file within JFileChooser without closing the dialogue -

i trying implement "save as" dialogue using jfilechooser. dialogue supposed give user ability type filename , click save, @ point new file object returned , created.

this works, running problem when try add dialogue. specifically, want create "file exists" dialogue using joptionpane warn user if trying create file same name pre-existing file (this common feature in many programs). dialogue prompts "file <filename> exists. replace it?" (yes/no). if user selects "yes", file object should returned normal. if user selects "no", jfilechooser should stay open , await selection/creation of file.

the problem can't find way cancel selection (if user chooses "no") and keep dialogue open. have code:

public void saveas() {     if (editors.gettabcount() == 0)     {         return;     }      final jfilechooser chooser = new jfilechooser();      chooser.setmultiselectionenabled(false);      chooser.addactionlistener(new actionlistener()     {         public void actionperformed(actionevent arg0)         {             file f =  chooser.getselectedfile();              if (f.exists())             {                 int r = joptionpane.showconfirmdialog(                      chooser,                      "file \"" + f.getname() +                      "\" exists.\nwould replace it?",                      "",                      joptionpane.yes_no_option);                      //if user not want overwrite                 if (r == joptionpane.no_option)                 {                     //cancel selection of current file                     chooser.setselectedfile(null);                 }             }         }     });      chooser.showsavedialog(this);      system.out.println(chooser.getselectedfile()); } 

this cancels selection of file if user selects "no" (that selected file upon closure of dialogue null). however, closes dialogue afterwards.

i prefer if dialogue remained open when happened. there way this?

override approveselection() method. like:

jfilechooser chooser = new jfilechooser( new file(".") ) {     public void approveselection()     {         if (getselectedfile().exists())         {             system.out.println("do want overwrite file?");             // display joptionpane here.               // if yes, super.approveselection()         }         else             super.approveselection();     } };
