Answer 1

您可以使用此

String FolderName="C:/name";//Write your complete path here 
try { 
     Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + FolderName); 
    } catch (IOException ex) { 
      Logger.getLogger(ClassName.class.getName()).log(Level.SEVERE, null, ex); 
    } 

Answer 2

這裏是一個例如你：

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); 
    } 
}
