package test;

public class TestCmd {
    public TestCmd(){}
   /* public  void main(String args[]){
        try {
          Process process = Runtime.getRuntime().exec("cmd.exe  /c  start  http://www.csdn.net");  //登入網站
          Process process = Runtime.getRuntime().exec("cmd.exe  /c  start  ping 10.144.98.100");  //調用Ping命令
        }catch (Exception  e)
        {
            e.printStackTrace();
            }  
        
      }
    }  */

//在項目下建立一個名為hello的檔案夾
    public static void main(String[] args) {
        System.out.println(System.getProperty("user.dir"));
        createFolder("hello");
      }

     private static void createFolder(String folderName) {
       String temp = System.getProperty("user.dir") + java.io.File.separator+ folderName;
       java.io.File f = new java.io.File(temp);
       f.mkdirs();
     }

}

在Java程式中擷取當前運行程式的路徑

import java.io.*;

public class Test {

       public static void main(String[] args) {

              File directory  = new File(".");

              try {

                     File newPath = new File(directory.getCanonicalPath()+"NewFolder");

                     newPath.mkdir();

              }catch(Exception exp)

              {

                     exp.printStackTrace();

              }

       }

}

//File directory       = new File(".");

//directory.getCanonicalPath();取得當前路徑

在Jsp頁面中調用Ping命令---PingIP.jsp

       is.close();  
       isr.close();  
       br.close();
