How to Save, Save As Java?

Hello I'm having a little bit of a problem with my text editor like program. I would like to have my Save feature work only if Save As has been called, and if Save is called that it appends the text From a JTextArea to the file created by Save As. I am using ActionListeners from JMenuItems to call the Save and Save As Actions. Here's the code for Save As:

FileDialog fileDialogSave = new FileDialog(frame, "Save", FileDialog.SAVE);
fileDialogSave.setVisible(true);        
String userProjectSavePath = fileDialogSave.getDirectory() + fileDialogSave.getFile();
File userProjectSave = new File(userProjectSavePath);
try (PrintWriter out = new PrintWriter(new BufferedWriter(new FileWriter(userProjectSave, true)))) {
userProjectSave.createNewFile();
String userProjectNameToSave = codeArea.getText();
out.println(userProjectNameToSave);
} catch (IOException e1) {
    e1.printStackTrace();
}

Both the Save and Save As are nested inside static class ActionSaveAs implements ActionListener { public void actionPerformed(ActionEvent e) { ... } }

The problem is I can't access the String userProjectSavePath in the Save class so I can't append the new text to the same file as in the Save As.

Instead, let your notional saveDocument() method invoke saveDocumentAs() if currentFile is null. The following outline suggests the approach taken in Charles Bell's HTMLDocumentEditor, cited here.

public void saveDocument() {
    if (currentFile != null) {
        // Save in currentFile
    } else {
        saveDocumentAs();
    }
}

public void saveDocumentAs() {
    // Check before overwriting existing file
}
