I would like to know the detail syntax for launching an .exe file (written in c ) from inside a java program .
Please give some help.

Hi dilse,

Taking for example your .exe file is named "abc.exe" and is in the same folder as your java program:-

import java.io.*;
public class example1
{
public static void main(String[] args)
{
Runtime rt = Runtime.getRuntime();
try {
Process extProcess = rt.exec("abc"
extProcess.waitFor();

// receive the output of external program
InputStream extInput = extProcess.getInputStream();
int bytesAvailable = extInput.available();
if (bytesAvailable > 0)
{
byte[] extInputData = new byte[bytesAvailable];
extInput.read(extInputData);
System.out.println(new String(extInputData));
}
}
catch (Exception e)
{
}
}
}

If you C program requires input from the user, the program will "hang" as the C program's console will be "hidden" so you will never be able to enter anything into the C program.
