【问题描述】：
如何将文件选择器的选定目录放入我当前的工作目录。我正在制作一个组织文件夹的项目，并在 Youtube 上找到了一个类似的项目，但它只在 Organizer.jar 文件所在的位置运行 而我想要做的是一个用户界面，它使用文件选择器直接选择文件夹目录，这样我就不会在任何我想组织文件夹的地方移动或复制 Organizer.jar 文件。
代码如下：
package my.GUI;
import java.awt.BorderLayout;
import java.awt.Component;
import java.awt.Dimension;
import java.io.File;
import java.nio.file.CopyOption;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.StandardCopyOption;
import java.util.Arrays;
import javax.swing.JFileChooser;
import javax.swing.JFrame;
import javax.swing.JInternalFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
import javax.swing.border.EmptyBorder;
