如何从文件选择器获取完整路径目录

JFileChooser chooser = new JFileChooser();
chooser.setCurrentDirectory(new java.io.File("."));
chooser.setDialogTitle("choosertitle");
chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
chooser.setAcceptAllFileFilterUsed(false);

if (chooser.showOpenDialog(null) == JFileChooser.APPROVE_OPTION) {
  System.out.println("getCurrentDirectory(): " + chooser.getCurrentDirectory());
  System.out.println("getSelectedFile() : " + chooser.getSelectedFile());
} else {
  System.out.println("No Selection ");
}
