利用Java調用可執行命令

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"); //登錄網站 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();取得當前路徑

在JSp頁面中調用Ping命令---PingIP.JSP

<%@ page language="java" contentType="text/Html; charset=gb2312" import="Java.io.*" %>

Ping IP測試頁面

<% Runtime runtime = Runtime.getRuntime(); Process process =null; String line=null; InputStream is =null; InputStreamReader isr=null; BufferedReader br =null; String ip="www.sina.com.cn"; //待Ping的地址 try { process =runtime.exec("ping "+ip); is = process.getInputStream(); isr=new InputStreamReader(is); br =new BufferedReader(isr); out.println("

");         while(  (line  =  br.readLine())  !=  null  )         {             out.println(line);             out.flush();         }         out.println("

"); is.close(); isr.close(); br.close(); } catch(IOException e ) { out.println(e); runtime.exit(1); } %>
