以下是您的示例：

import java.awt.Desktop;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;
import java.io.IOException;

import javax.swing.JButton;
import javax.swing.JFrame;

public class Main extends JFrame {
    File file = new File("C:\\");
    Desktop desktop = Desktop.getDesktop();

    public Main() {
        super("open folder demo/SuRu");
        JButton button = new JButton("Open C:\\");
        button.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent arg0) {
                try {
                    desktop.open(file);
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        });
        add(button);
        setBounds(100, 100, 200, 200);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
    }

    public static void main(String[] args) {
        new Main().setVisible(true);
    }
}
