I want to run a batch file through java program. The batch file itself runs a exe file with some filename as arguments. I tried this by creating a C program and running that exe through java. Is there any other way to run a batch file which itself runs a exe through java. Thanks in advance...

You could use Runtime.exec and pass it cmd /c /path/to/your/batch/script.
As of Java 1.5, you can also use ProcessBuilder.
Process p = new ProcessBuilder("cmd", "/c", "/path/to/batch/file").start();
The API docs for ProcessBuilder details a more complex setup with working directories and such.

public class CallingBatch {
public static void main(String[] args) {
Runtime run = Runtime.getRuntime();
try {
run.exec("cmd start /c C:/batfile.bat");
} catch (Exception e) {
e.printStackTrace();
}
System.out.println("FINISHED");
}
}
Hope this will help you.

To start with playing with the batch file you have to take some time to learn PROCESSBUILDER and Runtime classes.
Program:
class RunBatch
{
public static void main(String[] arg){
Runtime runtime = null;
try{
runtime.getRuntime.exec("CMD START /C D:/myBatchFile.bat");
}
catch(RuntimeException e){
e.printStackTrace();
}
}
}

My preferred method of starting any process from within java is to use ProcessBuilder
