利用Java调用可执行命令

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");  //登录网站          Process process = Runtime.getRuntime().exec("cmd.exe  /c  start  ping 10.144.98.100");  //调用Ping命令        }catch (Exception  e)        {            e.printStackTrace();            }                }    }  *///在项目下建立一个名为hello的文件夹    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程序中获取当前运行程序的路径



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();取得当前路径





在Jsp页面中调用Ping命令---PingIP.jsp
