如何在java文件中调用批处理文件？高分相送

如何在java文件中调用批处理文件？请高手写出部分代码，谢谢

执行本地代码的时候有几点要注意的，例如等待执行时间和截取输出流等，以下的代码本人试过，能运行的：

执行dos，windows命令：

import java.util.*;
import java.io.*;

class StreamGobbler extends Thread
{
InputStream is;
String type;

StreamGobbler(InputStream is, String type)
{
this.is = is;
this.type = type;
}

public void run()
{
try
{
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line=null;
while ( (line = br.readLine()) != null)
System.out.println(type + ">" + line);
} catch (IOException ioe)
{
ioe.printStackTrace();
}
}
}

public class GoodWindowsExec
{
public static void main(String args[])
{
if (args.length < 1)
{
System.out.println("USAGE: java GoodWindowsExec <cmd>");
System.exit(1);
}

try
{
String osName = System.getProperty("os.name" );
String[] cmd = new String[3];
System.out.println( osName);
if( osName.equals( "Windows 2000" ) )
{
cmd[0] = "cmd.exe" ;
cmd[1] = "/C" ;
cmd[2] = args[0];

}
else if( osName.equals( "Windows 95" ) )
{
cmd[0] = "command.com" ;
cmd[1] = "/C" ;
cmd[2] = args[0];
}

Runtime rt = Runtime.getRuntime();
System.out.println("Execing " + cmd[0] + " " + cmd[1]
+ " " + cmd[2]);
Process proc = rt.exec(cmd);
// any error message?
StreamGobbler errorGobbler = new
StreamGobbler(proc.getErrorStream(), "ERROR");

// any output?
StreamGobbler outputGobbler = new
StreamGobbler(proc.getInputStream(), "OUTPUT");

// kick them off
errorGobbler.start();
outputGobbler.start();

// any error???
int exitVal = proc.waitFor();
System.out.println("ExitValue: " + exitVal);
} catch (Throwable t)
{
t.printStackTrace();
}
}
}

Navigate yourself around pitfalls related to the Runtime.exec() method

[jFresH_MaN]

Runtime.getRuntime().exec("cmd /c C:\\abc.bat");

[kingfish]

Runtime.getRuntime().exec("cmd /c test.bat");
