　　package test;

/** * Add one sentence class summary here. * Add class description here. * * @author lxx * @version 1.0, 2004-11-16 */public class TestCmd {    public TestCmd(){}   /* public void main(String args[]){        try {        PRocess process = Runtime.getRuntime().exec("cmd.exe /c start http://www.csdn.net"); //登錄網(wǎng)站          Process process = Runtime.getRuntime().exec("cmd.exe /c start ping 10.144.98.100"); //調(diào)用Ping命令        }catch (Exception e)        {            e.printStackTrace();            }               }    } *///在項目下建立一個名為hello的文件夾    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程序中獲取當(dāng)前運行程序的路徑

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(dāng)前路徑

在jsp頁面中調(diào)用Ping命令---PingIP.JSP
