Java 打开文件夹

 package com.swing.demo;

 import java.io.File;
 import java.io.IOException;

 public class OpenDirTest {
     public static void main(String[] args) {
         try {
             java.awt.Desktop.getDesktop().open(new File("D:\\Java"));
         } catch (IOException e) {
             e.printStackTrace();
         }
     }
 }

备用方式:

 try {
             String[] cmd = new String[5];
             cmd[0] = "cmd";
             cmd[1] = "/c";
             cmd[2] = "start";
             cmd[3] = " ";
             cmd[4] = FILE_PATH;
             Runtime.getRuntime().exec(cmd);
         } catch (IOException e) {
             e.printStackTrace();
         }
