然后，可以使用JFileChooser类来创建一个文件选择对话框，并将其与按钮关联起来。当用户点击按钮时，可以通过JFileChooser选择文件，并将文件路径显示在文本框中。...java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.JButton; import javax.swing.JFileChooser...button.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { JFileChooser...fileChooser = new JFileChooser(); int result = fileChooser.showOpenDialog(frame);...if (result == JFileChooser.APPROVE_OPTION) { String filePath = fileChooser.getSelectedFile

第三步： 接下来我们需要获取到dimens原始文件，这里我们通过JFileChooser来获取文件，这里我们的类型是JFileChooser.FILES_ONLY只支持文件。...代码如下： 重点都已注释： JFileChooser jfc = new JFileChooser(); //只支持文件 jfc.setFileSelectionMode...(JFileChooser.FILES_ONLY); jfc.showDialog(new JLabel(), "选择"); File file = jfc.getSelectedFile
