how to get the values from command prompt

[tej]

hi all i have code which executes the .bat file from command prompt


import java.io.*;
class test{
public static void main(String arg[]){
try{
String command = "cmd /C start C:/test.bat ";
Runtime rt = Runtime.getRuntime();
Process pr = rt.exec(command);

}catch (IOException e) {
e.printStackTrace();
}
}
}


here is the query
how can i display the results which are executed by test.bat through java application.

[angryboy]

take a look at the Process API doc.

String command = "cmd /c @echo Hello World!";
...
Scanner scan = new Scanner(pr.getInputStream());
...

here is mycode

import java.io.*;
class parsingapplication1
{

public static void main(String args[]) throws IOException
{
Process process = Runtime.getRuntime().exec( "cmd /C start C:/test.bat" );

byte[] readBuffer = new byte[1024]; //created object for the byte class
StringBuilder stderrBuffer= new StringBuilder(); //created object for StringBuilder

InputStream errorIs = process.getErrorStream(); //to display errors
int bytesRead = errorIs.read( readBuffer );
while( bytesRead >= 0 )
{
stderrBuffer.append( new String( readBuffer, 0, bytesRead ) );
bytesRead = errorIs.read( readBuffer );
}
// do something with stderrBuffer

StringBuilder stdoutBuffer = new StringBuilder();
InputStream inputIs = process.getInputStream();
bytesRead = inputIs.read( readBuffer );
while( bytesRead >= 0 )
{
stdoutBuffer .append( new String( readBuffer, 0, bytesRead ) );
bytesRead = inputIs.read( readBuffer );
}
}

please check it once

Did you get any error message there in the above code. What you exactly going to do?

And also, seems to me you've misses the last closing bracts in the class. ;)
