As per https://docs.oracle.com/en/java/javase/18/docs/api/java.desktop/javax/swing/JFileChooser.html#%3Cinit%3E(), "Constructs a JFileChooser pointing to the user's default directory. This default depends on the operating system. It is typically the "My Documents" folder on Windows, and the user's home directory on Unix.", but on Windows 10 and above the default directory is "Documents" folder now, so the Javadoc need to be updated accordingly.
