JFileChooser fileChooser = new JFileChooser () ;
if ( f i leChooser . showDialog (NotepadFrame . this , "Save" )==
JFileChooser .APPROVEOPTION) {
File newFile = fileChooser . getSelectedFile() ;
try (PrintWriter fileWritter = new PrintWriter(newFile)) {
fileWritter .print(textArea.getText());

} catch (Exception exception) {

}

}

}

} );
...

}

In the above example, the code textArea.getText() gets the whole text from the text
area. Even though this text can be multiple lines, it can be stored as a single string. Next,
we call the print method to write the text to the file.
