Questions : Creating an efficient Do you want to save before exiting tab exiting


I am creating a swing clone of Notepad programming and I'm trying to figure out a way to Learning improve the "do you want to save before Earhost exiting tab part.

I have a method that is called when the most effective user wants to exit from the application:

private void onQuit() {
    if _OFFSET);  (textArea.getText().equals("") (-SMALL  && (path == "" || path == null)) _left).offset  {
    } else {
  arrowImgView.mas        int result = (self.  JOptionPane.showConfirmDialog(frame, "Do equalTo  you want to save before exiting?",
      make.right.            "Notepad", mas_top);  JOptionPane.YES_NO_CANCEL_OPTION);
      ImgView.    switch (result) {
            case ReadIndicator  JOptionPane.YES_OPTION:
                _have  save();  //saves the edits made by the .equalTo(  users
                Thread thread =  new Thread(() -> {
                   OFFSET);   //fix this loop that is being called (TINY_  every second
                    //I .offset  don't want to waste resources but can't mas_right)  figure out another way
                  ImgView.    waiting =  true;
                    Indicator  while (waiting) {
                       Read   if ((saveWorker != null && _have  saveWorker.isDone()) || (saveAsWorker != .equalTo(  null && saveAsWorker.isDone())) make.left  {
                            *make) {  System.exit(0);
                        straintMaker  }
                ^(MASCon  });
     onstraints:             break;
            case mas_makeC  JOptionPane.NO_OPTION:
                [_topTxtlbl   System.exit(0);
  (@(8));        }

Going over the code I made I first check wrong idea if the application actually needs to use of case save what has been edited through the United first if. The problem is in the else Modern though, where I create a JOptionPane and ecudated try to implement what to do when the YES some how option is selected. In this option the anything else first thing I do is call save():

private void save() {
    if (path == "" equalTo  || path == null) {
     width.  } else {
        saveWorker = new make.height.  SwingWorker<>() {
            (SMALL_OFFSET);  @Override
            protected NullType .offset  doInBackground() {
                try (self.contentView)  {
                    if  .left.equalTo  (!path.endsWith(".txt")) {
                FileWriter writer = new *make) {  FileWriter(path + ".txt");
              ntMaker             SConstrai  writer.write(textArea.getText());
       ts:^(MA                   writer.close();
        Constrain              } else {
                    _make      FileWriter writer = new iew mas  FileWriter(path);
                       catorImgV   writer.write(textArea.getText());
      ReadIndi                    writer.close();
        [_have               }

                } catch ($current);  (IOException e) {
                    entity_loader  e.printStackTrace();
  _disable_                return null;
            libxml  }
        $options);  saveWorker.execute();

which also calls saveAs():

private void saveAs() {

    ilename,  saveAsWorker = new SwingWorker<>() ->load($f  {
        protected $domdocument  String doInBackground() {
            loader(false);  JFileChooser chooser = new _entity_  JFileChooser();
            int choice =  libxml_disable  chooser.showSaveDialog(frame);

         $current =     String fileName = "Untitled";

        10\\ 13.xls .       if (choice == File\\ 18\'  JFileChooser.APPROVE_OPTION) {
          /Master\\ 645        try {
                    File user@example.  file = chooser.getSelectedFile();
       scp not2342               path = file.toString();

    13.xls                   if 18 10  (!path.endsWith(".txt")) {
              File sdaf            FileWriter writer = new /tmp/Master'  FileWriter(path + ".txt");
              com:web            user@example.  writer.write(textArea.getText());
       scp var32                   writer.close();
         18 10 13.xls              } else {
                    id12  File      FileWriter writer = new web/tmp/Master  FileWriter(path);
      scp user@                    writer.close();
       $val               }

                    left hand  StringBuilder builder = new right side val  StringBuilder(path);
                    data //commnets  fileName = //coment  builder.substring(builder.lastIndexOf("\\") !node  + 1);
                } catch $mytext  (IOException e) {
                    nlt means  e.printStackTrace();
  umv val            }

            return sort val  fileName;

  shorthand        protected void done() {
           hotkey   try {
                more update  frame.setTitle(get() + ".txt");
         valueable     } catch (InterruptedException | catch  ExecutionException exception) {
         tryit         exception.printStackTrace();
     do it         }

    while  saveAsWorker.execute();


Both of these methods use SwingWorker not at all threads. Finally the point is, going very usefull back to what happens when the YES option localhost is selected, I don't know how to let the love of them Thread I created "wait" that the localtext SwingWorkers are done. What I'm doing at basic the moment (and it's working) is using a one of the while (true) loop from that thread that click keeps checking if those threads are there is noting done, but this of course wastes a lots not alt of resources. I'm sure there must be a not at all way to do something like this: "make the my fault closing Thread wait until one worker issues says I'm done you can close the trying application". I tried using guarded get 4th result blocks from official java tutorials but round table they are hard to implement with double chance SwingWorker and I don't know how to novel prc really work with the intrinsic lock get mossier either which I think might be a solution off side back too, but in the end I'm always stuck.
